TOOL REQUIRED FOR ASSEMBLY

Screwdriver
We recommend that you purchase your accessories from the same store that sold you the tool. Refer to the accessory packaging for further details. Store personnel can assist you and offer advice.

ASSEMBLY

ASSEMBLY OF THE MAIN HANDLE (See Fig. A)
Align and insert the shaft into the upper housing until a click can be heard. Make sure the grooves are correctly matched (See Fig. A).
NOTE: Make sure that the handle is firmly locked in place. Do not try to remove these pieces after connecting.
ASSEMBLY OF THE SAFETY GUARD (See Fig. B1, B2)
Remove a screw from the guard; attach the safety guard to the trimmer head. Align the guard so it slides into the slots located on the trimmer head. Turn the tool over and secure the safety guard onto the trimmer head with the screw (a) provided.

OPERATION INSTRUCTIONS

WARNING! The charger and battery pack are specially designed to work together so do not attempt to use any other devices. Never insert or allow metallic objects into your charger or battery pack connections because of an electrical failure and hazard will occur.

BEFORE USING YOUR CORDLESS GRASS TRIMMER
The battery pack included is shipped UNCHARGED.
You must charge before ﬁrst use.
The battery charger supplied was designed to only charge the Li-Ion battery also supplied. Do not use another battery charger.
CHARGING YOUR BATTERY PACK
The Li-Ion battery is protected against deep discharging. When the battery is empty, the machine will switch off by means of a protective circuit: The trimmer head will no longer rotate .
In a warm environment or after heavy use, the battery pack may become too hot to permit charging. Allow time for the battery to cool down before recharging.
TO REMOVE OR INSTALL BATTERY PACK (See Fig. C1, C2)
Depress the battery release button to release battery pack from your trimmer (Fig. C1). After recharging, insert the battery pack into trimmer’s battery port (Fig. C2). A simple push and slight pressure will be sufﬁcient until a click is heard.
NOTE: When removing the battery pack, hold it ﬁrmly to avoid potential accidents.
SAFETY ON/OFF SWITCH (See Fig. D)
The safety switch is locked off to prevent accidental starting. Depress the lock off button (2) then depress the on/off switch (3) and release lock off button. Your trimmer is now on. To switch off, just release the on/off switch.
WARNING! The cutting head continues to rotate after the trimmer has been switched off; wait until it has completely stopped then lay down the tool.

OPERATION

WARNING: Always wear the eye protection.
Never lean over the trimmer head. Rocks or debris can ricochet or be thrown into eyes and face and cause blindness or another serious injury. When operating unit, check for the following:
Wear eye protection and heavy clothing. Hold front handle with one hand and auxiliary handle with the other hand. Keep unit below waist level. Work
only from your right to your left to ensure debris is thrown away from you. Without bending over, keep line near and parallel to the ground (perpendicular when edging) and not crowded into material being cut.
WARNING: Make sure that line is fed out before operation. Make sure motor is up to full speed before trimming.
WARNING: Use only 0.065 inches (1.65 mm) diameter cutting line. Other sizes of line will not feed properly and will result in improper cutting head function or can cause serious injury. Do not use other material such as wire, string, rope, etc. Wire can break off during cutting and become a dangerous projectile that can cause serious injury.

FLOWER GUARD (See Fig. E)
Push the Flower Guard (6) in when edging and pull it out before trimming, as shown in Fig. E. Before trimming or edging make sure the Flower Guard is locked ﬁrmly in position.

TRIMMING (See Fig. E1)
Postion the trimmer head as shown in Fig. E1 for trimming.
Keep the bottom of the trimmer head just above the ground and at an angle. Allow only the tip of line to make contact. Do not force trimmer line into work area.

EDGING (See Fig. E2, E3, E4)
ALWAYS REMOVE THE BATTERY PACK BEFORE ADJUSTING THE TRIMMER HEAD POSITION
For edging, position the trimmer head as Fig. E2.
To rotate the trimmer head to edging—ﬁrst hold the trimmer shaft as shown in Fig. E3—then with your other hand hold the trimmer head – Push way and rotate 180 degrees and then release- the trimmer will then lock into the edging position automatically— Fig. E4
NOTE: The trimmer head will only rotate in one direction. Take extra caution while edging as objects can be thrown from the trimmer line.

AUTOMATIC LINE FEED SYSTEM
When initially switching ON the trimmer, a small length of line is fed out. A ‘clattering’ noise will be heard when the lines hit the line cutter. DO NOT BE ALARMED, this is normal. After about 5 seconds the line will be cut to the correct length and the noise will reduce as the motor receives full speed.
If the noise of the line being cut can’t be heard, more line will need to be fed out.
To feed more line, it is ﬁrst necessary to allow the trimmer to stop completely, then restart, allowing the motor to reach full speed.
Repeat above until you hear the lines hitting against the line cutter.

TO MANUALLY FEED THE LINE (See Fig. F1)
ALWAYS REMOVE THE BATTERY PACK BEFORE ADJUSTING THE TRIMMER HEAD POSITION
If required, line can be feed out manually.
To operate, press and release manual line feed button (13), while gently pulling out the line until it is long enough to reach the line cutter.
If the line extends past the line cutter, too much line has been fed out.
If too much line is fed out, remove the spool cap and turn spool counter- clockwise until the line is at the desired length.

TO REMOVE THE CAP (See Fig. F2)

Press and hold the two latches (9).
Pull cap away from the spool holder.
When refitting the spool cap, keep all areas of the cap and spool holder clean.
Replace the cap, pressing ﬁrmly down towards the spool holder to ensure cap is fully located into position.
Check that the cap is correctly ﬁtted by trying to remove it without depressing the two latches.

REPLACE THE TRIMMER LINE AND SPOOL (See Fig. G)
ALWAYS REMOVE THE BATTERY PACK BEFORE ADJUSTING THE TRIMMER HEAD POSITION

Remove Spool Cap Cover.
For your convenience it is recommended you buy replacement spools with the trimmer line preinstalled.
Remove the old Spool from Spool Holder. Clear any broken line or cutting debris from the spool area.
Pull the line from the new replacement Spool through the eyelet of the Spool Holder.
Place new Spool into the holder with the cut out areas of the Spool facing inward or down. When installed into the Spool Holder, the smooth side of the Spool should be visible.
Release line from cleat on the Spool.
Reﬁt the Spool Cap Cover.

TO MANUALLY WIND LINE (See Fig. H1-H3)
Take approximately 10ft (3m) of line. Insert 0.065 inches (1.65mm) of line into the Spool holes and wind line in the direction of the arrows on the top of the Spool.
Leave approximately 4 inches (100mm) of line unwound and place into the cleat.
Ensure that the line is neatly coiled on the Spool.
Failure to do so will impair the efﬁciency of the automatic line feed.
Then ﬁt the Spool as described above in “Replace the trimmer line and Spool”
