APPLICATIONS
You may use this product for the purposes listed
below:
 Basic limbing, felling, and woodcutting
ADDING BAR AND CHAIN LUBRICANT
See Figure 6.
NOTE: Chain saw comes from the factory with
no bar and chain lubricant added. Level should
also be checked after every 20 minutes of use and
refilled as needed.
Use a bar and chain lubricant designed for
lubricating chain saw chains. They are formulated
to extend bar and chain life by protecting against
wear and reducing friction and heat.
NOTE: Do not use dirty, used, or otherwise
contaminated lubricants. Damage may occur to
the bar or chain.
 Disconnect chain saw from power supply.
 Remove oil cap.
 Carefully pour the bar and chain lubricant into
the tank.
 Wipe off excess lubricant.
 Check and fill the oil tank when quick view oil
indicator is below the second to last indicator
line.
 Repeat as needed.
OPERATION
NOTE: It is normal for lubricant to seep from the
saw when not in use. To prevent seepage, empty
the oil tank after each use then run for one minute.
When storing the unit for a long period of time
(three months or longer) be sure the chain is lightly
lubricated; this will prevent rust on the chain and
bar sprocket.
NOTICE:
Before each use, check to make sure that the
chain is properly tensioned. A cold chain is
correctly tensioned when there is no slack on
the underside of the guide bar, the chain is snug,
and it can be turned by hand without binding.
During normal saw operation, the temperature
of the chain increases. The drive links of a
correctly tensioned warm chain will hang
approximately .050 in. out of the bar groove.
See the Adjusting the Chain Tension
instructions in the Maintenance section of this
manual to properly adjust the chain tension.
