NOTE: The best way to hold a log while bucking is to use
a sawhorse. When this is not possible, the log should
be raised and supported by limb stumps or by using
supporting logs. Make sure the log to be cut is securely
supported.
Bucking Using a Sawhorse (Fig. 10)
a.
Hold the saw firmly with both hands and keep the saw

Maintenance

The following suggestions pertain to the daily maintenance
of the chain saw. In the event of tool 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 to be replaced.
• Check that there is sufficient oil.
• Clean the chain brake and ensure that it works properly.
• Check the bar wears.

• Ensure that the 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.
• Ensure that the oil reservoir and the oil filter are clean. This
chain saw meets all legislation requirements. In order to
avoid injures, all repairs are to be done by qualified staff at
an authorized service facility.

Chain Sharpening

It is highly recommended to replace the chain once it loses
its ability to cut cleanly and safely. It is possible, however,
to sharpen the existing chain if the sharpening is carefully
performed. To sharpen the chain, refer to Fig. 11 below and
proceed as follows:
• Disconnect the tool from the mains supply.
• Don protective gloves.
• Ensure that the chain has sufficient tension.
• 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 the inside towards the outside only.
• Sharpen each tooth equally by using the same number of
strokes.
• Check the safety depth gauge height every 5-chain
sharpenings.
• 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.
