If you cannot cut the timber right through with a single stroke: Apply light
pressure to the handle and continue sawing and draw the chain saw back
a little; then apply the spike bumper a little lower and finish the cut by
raising the handle.
NOTICE: When making several cuts, switch the chain saw off between cuts.
If the upper edge of the bar is used for cutting, the chain saw may be de-
flected in your direction if the chain becomes trapped. For this reason, cut
with the lower edge, so that the saw will be deflected away from your
body.

MAINTENANCE

In order to maintain product SAFETY and RELIABILITY, repairs, any other
maintenance or adjustment should be performed by Authorized or Factory
Service Centers, always using appropriate replacement parts.
1. Cleaning the guide cover : Chips and sawdust will build up in the guide bar
groove. They may clog the bar groove and impair the oil flow. Clean out the
chips and sawdust every time when you sharpen or replace the saw chain.
3. Cleaning the oil discharge hole: Small dust or particles may be built up in
the oil discharge hole during operation. These dust or particles may impair
the oil to flow and cause an insufficient lubrication on the whole saw chain.
When a poor chain oil delivery occurs at the top of guide bar, clean the oil
discharge hole as follows.
a.Remove the sprocket cover and saw chain from the tool.
b.Remove the small dust or particles using a slotted screwdriver with a slen-
der shaft or the like.
c.Insert the battery cartridge into the tool. Pull the switch trigger to flow
built-up dust or particles off the oil discharge hole by discharging chain oil.
d.Remove the battery cartridge from the tool. Reinstall the sprocket cover
and saw chain on the tool.

When you cut a wood under tension, cut the pressured side (A) first. Then
make the final cut from the tensioned side (B). This prevents the bar from
becoming trapped.
Before carrying the tool, always apply the chain brake and remove the bat-
tery cartridges from the tool. Then attach the guide bar cover.

nance. Never use gasoline, benzine, thinner alcohol or the like. Discoloration,
deformation or cracks may result. Always be sure that the tool is switched off
and the battery cartridge is removed before attempting to perform inspection
or maintenance.
2. Cleaning the sprocket cover : Chips and saw dust will accumulate inside of
the sprocket cover. Remove the sprocket cover and saw chain from the tool
