Instructions For Periodic Maintenance - Makita UC100D Betriebsanleitung

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.
► Fig.31
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.
► Fig.32
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.
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.

3. 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.
