Checking The Chain Lubrication; Adjusting The Chain Lubrication - Makita DCS6400 Instruction Manual

Checking the chain lubrication

Never work with the chain saw without sufÞ cient chain lubri -ca-
tion. Otherwise the service life of the chain and guide bar will
be reduced. Before starting work check the oil level in the tank
and the oil feed.
Check the oil feed rate as described below:
Start the chain saw (see „Starting the engine").
Hold the running chain saw approx. 15 cm above a trunk or the
ground (use an appropriate base).
If the lubrication is sufÞ cient, you will see a light oil trace be-
cause oil will be ß ung off the sawing device. Pay attention to the
direction the wind is blowing and avoid unnecessary exposure
to the oil spray!
Note:
After the saw has been turned off it is normal for residual chain
oil to drip from the oil feed system, the guide bar and the chain
for a time. This does not constitute a defect!
Place the saw on a suitable surface.

Adjusting the chain lubrication

The engine must be switched off.
You can adjust the oil pump feed rate with the adjusting screw
(1). The adjusting screw is on the bottom side of the housing.
The oil pump comes factory-set to a medium feed rate.
To change the feed quantity use the screwdriver and adjust the
adjusting screw in the following way:
• Turn to the right to reduce the feed rate.
• Turn to the left to increase the feed rate.
Even very small adjustments to the adjusting screw (1) can
inß uence the oil ß ow rate. While working make sure there is
enough chain oil in the tank. If necessary, add oil.
To ensure troublefree operation of the oil pump the oil guide
groove at the crank case (2) and the oil inlet bore in the guide
bar (3) must be cleaned regularly.
Note:
After the saw has been turned off it is normal for residual chain
oil to drip from the oil feed system, the guide bar and the chain
for a time. This does not constitute a defect!
Place the saw on a suitable surface.
