Black & Decker's policy is one of continuous improvement to our products and, as such, we reserve the right to change product specifications without prior notice.
Double insulation
Your trimmer is double insulated. This means that all external metal parts are electrically isolated from the power supply. This is achieved by placing an extra insulation barrier between the electrical and mechanical parts. Double insulation means greater electrical safety and obviates the necessity of having your trimmer earthed.

GL340 UK p02-11 w/p

24/3/00, 2:16 pm

Electrical safety (UK only)

Your trimmer should always be switched off

at the mains before disconnecting any plug and socket connector or extension cables.

Fuse replacement
If your trimmer is supplied with cable fitted with a non-re-wireable plug:
· The plug is fitted with a 5 amp fuse which
is the recommended fuse for your trimmer.
· Only use replacement fuses which are
approved to BS1362.
· When changing the fuse in your plug,
always ensure the fuse cover is refitted. If the fuse cover is missing or damaged do not use the plug.

Note: Fuses do not give personal protection against electric shock.

Plug replacement
· Disconnect the plug from the supply.
· Cut off the plug and dispose of
immediately. Insertion of a detatched plug into a 13 amp socket outlet may result in electric shock.
· Only fit BS1363A approved plugs fitted
with the correctly rated fuse.
· The cable wire colours, or a letter, will be
marked at the connection points of most good quality plugs. Attach the wires to their respective points in the plug (see below). Brown is for "Live" (L) and blue is for "Neutral" (N).
· Before replacing the top cover of the
mains plug ensure that the cable restraint is holding the outer sheath on the cable firmly and that the two leads are correctly fixed at the terminal screws.

Warning! Never connect live or neutral wires to the earth pin marked "E" or .
Note: Do not wire an extension cable directly into your trimmer yourself. Instead, take your trimmer to your nearest Black & Decker service agent. 4

Increased safety can be obtained by having a qualified electrician install a high sensitivity (30mA) circuit breaker in the house wiring. If you do not have such a circuit breaker installed, or you do not wish to have one installed, then we strongly recommend that the electrical power to your trimmer be supplied through a high sensitivity residual current device (RCD). The RCD is designed to provide a high degree of personal protection against harmful electric current should fault conditions occur.
Warning! The use of an RCD or other circuit breaker unit does not release the operator of your trimmer from the safety instructions and safe working practices given in this manual.

Cordset replacement - Australia and New Zealand
If the replacement of the supply cord is necessary, this has to be done by the manufacturer or his agent in order to avoid a safety hazard.

The following five sections only refer to products supplied without a cable.

Cable connection system (UK only)

Black & Decker continually make every effort to achieve the highest standards in performance, quality and reliability and recommend the use of a new outdoor cable connection system.

The new system gives additional protection against the possibility of water or moisture entering into the cable connector during normal use.

Note: The new connection system does not release the operator of the machine from the safety precautions and safe working practices given in this user manual. Particular attention is drawn to the coupler system as being "weather resistant" and not suitable for immersion, submersion or being subjected to water jets. Care should be taken to prevent the cable from lying or trailing through pools of water or from splashing with hose pipes.

The new cable system is available in various lengths through most major DIY retail outlets:

A6615

20m heavy duty cable, new socket 13 amp plug

A6616

20m heavy duty cable, new socket 13 amp plug and cable tidy system

A6617

30m heavy duty cable, new socket 13 amp plug and cable tidy system

GL340 UK p02-11 w/p

24/3/00, 2:16 pm

Existing cable systems (UK only)
If you already own an outdoor cable system, we recommend that you replace the existing `female' cable connector with the new `female' connector (see below) which is supplied loose in the carton. (Please read the section entitled "Fitting the `female' connector".)
old `female' connector new `female' connector
Should you wish to convert more than one cable system, the new female connector is available as an accessory from most major DIY retail outlets and from Black & Decker service agents (cat. no. A6624S).
Existing powered garden tools (UK only)
To connect existing Black & Decker garden power tools to the new system you will require an adaptor (see below). This is available as an accessory from most major DIY retail outlets (cat. no. A6623S).

ENGLISH

`female' connector

`male' connector

Warning! Never wire an extension cable with anything other than the `female' connector supplied and a 13 amp BS1363A approved plug with the recommended fuse. Never wire a `male' connector to your extension cable and never wire an extension cable with a plug of any kind at each end of the cable. This is extremely dangerous and results in the pins being live which may cause a fatal electric shock.

Warning! This adaptor is only suitable for products rated up to 500W.
It is not recommended for use with the following:
Hover mowers Rotary mowers with grass collection Chainsaws Shredders Blowervacs.
Please contact your local service agent should you require further advice.

Fitting the `female' connector (UK only)
To remove the cover, unscrew the fixing screw until it is free of the nut which is located in the hexagonal recess on the underside of the connector. Take care not to lose the nut if it falls out. There is no need to completely remove the fixing screw as it is intended to remain captive in the cover. The cover can now be removed by applying pressure as shown below.
apply pressure here

Fitting your own extension cable (UK only)
· When fitting your own extension cable fit a
13 amp plug (see "Fitting the mains plug") to one end of the cable and a `female' connector (supplied loose in the carton) to the other end (see opposite). For wiring instructions see the following sections.
· A `male' connector is already attached to the
electrical supply cable on your mower and is designed to be non-rewireable (see opposite). This should not be removed. Should the cable and plug become damaged or need replacing, please return your mower to your local Black & Decker service agent.

The extension cable contains two wires which are colour coded for easy recognition; brown is for `Live' (L) and blue is for `Neutral' (N). The female connector is marked `L' for live and `N' for neutral. These markings are located inside the body near the terminal screws (see opposite, figure a). With the connector cover removed, lift out the cable protector and proceed as follows:
· Pass the cable through from the narrow end of
the cable protector (see opposite, figure a).
· Prepare the cable ends to the specified strip
lengths (see opposite, figure b).

· Remove cable clamp (see opposite, figure a).
Take care of loose parts.
· To connect the extension cable to the connector
terminals, unscrew the terminal screws until the clamp washers have lifted just enough to enter the conductor between the raised washer and the terminal (see below). Connect the brown lead to `L' and the blue lead to `N'.
Note: There is no need to remove the terminal screws. Connections are not to be made under the screw heads.

· Locate the cable and cable protector into the
body correctly (see below, figure a). Then fit the cable clamp over the outer sheath of the cable and screw down until the screws are fully home. Failure to do this may result in the cover not fitting correctly to the connector body.
· Before replacing the cover of the `female'
connector make sure that the cable clamp is holding the outer sheath of the cable firmly with screws fully home and that the two leads are correctly fixed at the terminal screws and are not taut (see below, figure a).
· Place the cover onto the body assembly
ensuring that it seats flat, then retighten the fixing screw into the nut until the cover is securely held (see below, figure c).
· Finally check that the cable protector is secure
and that there are no gaps between the cover and the connector body.

Preparing your trimmer for use (Fig. C - E)

· Take your trimmer, guard and parts pack
out of the carton.

· Remove the guard screws from the
parts pack.

C · Place the guard (6) over the spool housing (13) on your trimmer taking care that the line (5) does not become stuck between the two parts.

D · Align the arrow (10) on the guard (6) with the square marking (9) on your trimmer body and push the guard upwards until it contacts the underside of the body. Now slide the guard forward until the square marking on the guard aligns with the square marking on your trimmer body. Ensure that the ridge on the guard has located in the slot on your trimmer body.

· Once the guard is in position, secure with
the two guard screws which go through

the guard screw holes (11) and into your

trimmer body.

· In transit, the end of the cutting line (5) is
taped to the side of the spool cover. Please discard the tape to release the length of line. There should be a minimum length of 9cm (3.5") of cutting line protruding from the spool housing before you use your trimmer.

Note: When your trimmer is operated for the first time, any excess line will be cut off by the line trimming blade (7) housed in the guard. This is also the case for any subsequent line adjustment. Because line cut off by the blade in the guard may be ejected, it is important that the amount of excess line is kept to a minimum. Where an excessive amount of line is pulled out, the line should be cut back to the outside of the guard before switching on your trimmer. Cut the line off on your trimmer blade by hand.

· Always ensure that the spool cover is
secure before and after use.

How to use your trimmer (Fig. B)
To switch on your trimmer press the switch lever. To switch the unit off, release the switch lever.
In order to get the most from your trimmer, please learn the following techniques. Do not be impatient, you will obtain the best results by experience and by following these simple rules.
B1 Do not use your trimmer without its guard.

GL340 UK p02-11 w/p

24/3/00, 2:17 pm

B2 Do not cut wet grass, best results are achieved when the grass is dry.
B3 Cut at an angle and with the tip of the nylon line. Your trimmer is balanced to operate at this angle.
B4 Swing your trimmer gently from side to side.
B5 Do not overload your trimmer. It operates best at high speeds.
B6 On long grass, start at the top.
B7 Take small cuts.
B8 If your trimmer features a cord restraint, loop a length of cord through the restraint to prevent the plug and socket coming apart accidentally if the cord is pulled.

How to fit a new spool of cutting line (Fig. F & G)

· Disconnect your trimmer from the
power supply.

· Remove the spool cover by pushing the
two spool cover tabs (12) inwards and

upwards (Fig. F), then pull off (it is not

necessary to push both tabs in at the

same time). The empty spool can now

be withdrawn from the drive shaft.

· Remove any dirt or grass that may have
collected inside the spool housing and cover.

· Unwind approximately 9cm (3.5") of
cutting line (5) from the new spool (15) and temporarily park the cutting line end in one of the `L' shaped slots to prevent the line unravelling.

G · Feed the cutting line through the eyelet (14) and then push the spool onto the centre drive shaft while pulling the free end of the line to release it from the `L' shaped slot. To fully seat the spool, rotate as necessary, taking care not to trap the cutting line underneath the spool and making sure that there is a minimum of 9cm (3.5") protruding from the spool housing.

· Replace the spool cover by aligning
both tabs on it (12) with the slots in the spool housing and pushing them into place. Make sure that both tabs are securely located.

ENGLISH
How to wind new line onto an empty spool (Fig. H & J)
H · A maximum of 10 metres of new cutting line can be wound onto the empty spool. The spool has an `Indicator' to help you avoid winding an excessive quantity of cutting line on the spool, as too much will prevent the automatic feed system from functioning. · Remove any remnant of old cutting line from the spool (15).
J1 · Push the end of the new cutting line into one of the two retaining holes (17) provided in the spool (15) and insert 20mm. · Bend the cutting line over, pulling it through the adjacent `L' shaped slot. The cutting line should now be firmly anchored to the spool and you may proceed to wind it on in the direction of the arrow (16).
J2 · Take time to wind the cutting line on neatly, in layers. Do not criss cross. · When you have wound on sufficient cutting line, temporarily park it in one of the `L' shaped slots to prevent the spool unravelling, ensuring you leave a minimum of 9cm (3.5") protruding. · Fit the spool and spool cover (8) to the spool housing as described for fitting a new spool.
Replacement line
A new spool containing 10 metres of nylon line may be purchased from your Black & Decker agent. Alternatively, replacement packs containing 25 to 50 metres of line are available. For maximum reliability never put on a heavier or lighter line (eg. fishing line) which will prevent the automatic feed from functioning, cause motor failure or reduce cutting performance.
Care and maintenance · For the best performance, please keep the nylon
line, spool and air slots in your trimmer body clean. Use a dry brush or cloth to remove grass, sap or other dirt.
· Plastic parts may be cleaned by using a mild
soap and a cloth dampened with hot water. Do not use any other type of detergent, cleaner
7

GL340 UK p02-11 w/p

24/3/00, 2:17 pm

or solvent which might contain chemicals that could seriously damage the plastic. Do not spray your trimmer with water.
· Self lubricating bearings are used in this tool and
so lubrication is not required.
Fault finding
Before checking your trimmer for any faults, disconnect it from the mains.
· If your trimmer will not start, check that the
power cord is properly connected. If this does not work, check your power point. Finally, check the fuse and wiring on the cable extension plug (UK only).
· If the automatic line feed fails to operate, it could
be for one of the following reasons:
Line too short or line jammed on spool
· Disconnect your trimmer from the power
supply.
· Remove the spool cover (8) by pushing both
tabs (12) inwards and upwards (Fig. F).
· Lift the spool (15) approximately 6mm (1/4")
from the spool housing (13), while pulling the cutting line (5). This will allow you to lengthen the line while clearing any line jammed inside the spool. Ensure there is a minimum of 9cm (3.5") protruding from the spool housing.
· Rotate the spool as necessary to fully seat
the spool and replace the cover by aligning both tabs on the cover with the slots in the spool housing and push into place. Ensure that both tabs are securely located.
Line still jammed on spool or broken inside spool housing
· Disconnect the power supply and remove
the cover, as previously described.
· Lift out the spool (15) completely, holding the
coiled cutting line in place to prevent it unravelling from the spool (Fig. J).
· Carefully unwind the cutting line (5) from the
spool until any crossed or trapped loops are cleared. Rewind the cutting line evenly, in the direction of the arrow (16) on the spool.
· Temporarily park the cutting line end in one
of the `L' shaped slots to prevent the spool unravelling. Ensure you leave a minimum of 9cm (3.5") protruding.
· Turn the lever (18) backwards and forwards
to ensure it operates freely (Fig. K).
· Remove any dirt or grass that may have
collected inside the spool housing and cover.
· Feed the end of the line through the eyelet
(14) and then push the spool into the centre drive shaft while pulling the free end of the
8

line to release it from the `L' shaped slot. To fully seat the spool, rotate as necessary, taking care not to trap the line underneath the spool, and making sure that there is a minimum of 9cm (3.5") of line protruding from the spool housing.
· Finally, replace the cover as previously
described.
