MAINTENANCE
SIDE PLATE ANGLE
• Maintain the depth gauge at a clearance of 1/32 in. (0.6 mm). Use a depth gauge tool
for checking the depth gauge clearances.
• Every time the chain is led, check the depth gauge clearance.
• Use a at le and a depth gauge jointer to lower all gauges uniformly. Use a 1/32 in.
• (0.6 mm) depth gauge jointer. After lowering each depth gauge, restore original shape
by rounding the front. Be careful not to damage adjoining drive links with the edge of
the le.
• Depth gauges must be adjusted with the at le in the same direction the adjoining
cutter was led with the round le.
• Use care not to contact cutter face with at le when adjusting depth gauges.

MAINTAINING THE GUIDE BAR
Every week of use, reverse the guide bar on the saw to distribute the wear for maximum bar
life.
The bar should be cleaned every day of use and checked for wear and damage. Feathering or
burring of the bar rails is a normal process of bar wear. Such faults should be smoothed with a
le as soon as they occur. A bar with any of the following faults should be replaced:
• Wear inside the bar rails that permits the chain to lay over sideways
• Bent guide bar
• Cracked or broken rails
• Spread rails
Lubricate guide bars weekly with a sprocket at their tip. Using a grease syringe,
lubricate weekly in the lubricating hole. Turn the guide bar and check that the
lubrication holes and chain groove are free from impurities.
