Chain Sharpening; Maintenance - sunjoe SWJ701E Operator's Manual

NOTE: The best way to hold a log while bucking is to use
a saw horse. When this is not possible, the log should
be raised and supported by limb stumps or by using
supporting logs. Be sure the log being cut is securely
supported.
BUCKING USING A SAWHORSE (Fig. 11)
a. Hold the saw firmly with both hands and keep the saw
to the right of your body while cutting.
b. Keep the left arm as straight as possible.
c. Keep weight on both feet.

MAINTENANCE

The following suggestions deal with the daily maintenance
of the chainsaw. In the event of failure contact an authorized
service center.
• Ensure that the electric power cord is not damaged.
• Ensure that the motor and cooling slots are unobstructed.
• If there is a reduction in motor power, the carbon brushes
may need replacement.
• Check there is sufficient oil.
• Clean the chain brake and ensure that it works properly.
• Check the bar wears.
• Ensure that oil-ways are unobstructed.
• Clean the chain guide on the bar.
• Check the chain tension, sharpen the blades and check
their condition.
• Check the guide bar sprocket.

chainsaw meets all legislation requirements; in order to
avoid injures all repairs are to be done by qualified staff in
an authorized service centre.

CHAIN SHARPENING

It is highly recommended that, once the chain loses it's ability
to cut cleanly and safely, it is replaced. It is possible, however,
to sharpen the existing chain if done carefully. To sharpen the
chain refer to Fig. 12 below and proceed as follows:
• Disconnect from the mains supply.
• Don protective gloves.
• Ensure the chain is correctly tensioned.
• Engage the chain brake to lock the chain on the bar.
• Use a round file whose diameter is 1.1 times the cutting
tooth depth.
• File at an angle perpendicular to the bar, and 38° to the
direction of travel.
• File each tooth from inside towards outside only.
• Sharpen each tooth equally by using the same number
of strokes.
• Check the safety depth gauge height every 5-chain
sharpening.
• If the depth gauges are also trimmed it is essential that the
original profile be restored.
• Use a depth gauge-measuring instrument to check the
height of the depth gauge. Depth gauge measuring jigs are
available from most reputable tool merchants.
