Cleaning The Guide Bar - Makita EY402MP Manuel D'instruction

— After sharpening the chain, check the height of the
depth gauge using the chain gauge tool (optional
accessory).
— Remove any projecting material, however small,
with a special flat file (optional accessory).
— Round off the front of the depth gauge again.

Cleaning the guide bar

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.
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 then clean the chips and saw dust.
Cleaning the oil discharge hole
Small dust or particles may be built up in the oil dis-
charge 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.
1. Remove the sprocket cover and saw chain from
the tool.
2. Remove the small dust or particles using a slotted
screwdriver or the like.

Replacing the sprocket
CAUTION:
A worn sprocket will damage a
new saw chain. Have the sprocket replaced in this
case.
Before fitting a new saw chain, check the condition of
the sprocket. If the sprocket is worn or damaged, ask
