WARNING
Failure to replace or repair a damaged chain can cause
serious injury.
TOP PLATE FILING ANGLE
See figure 52.
■ Correct 30° – file holders are marked with guide marks
to align file properly to produce correct top plate angle.
■ Less than 30° – for cross cutting.
■ More than 30° – feathered edge dulls quickly.
SIDE PLATE ANGLE
See figure 53.
■ Correct 80° – produced automatically if you use the
correct diameter file in the file holder.
■ Hook – "Grabs" and dulls quickly, increases the
potential of kick-back. Results from using a file with a
diameter too small or a file held too low.
■ Backward slope – needs too much feed pressure,
causes excessive wear to the bar and chain. Results
from using a file with a diameter too large or file held
too high.
MAINTAINING DEPTH GAUGE CLEARANCE
See figure 54 - 56.
■ Maintain the depth gauge at a clearance of 0.6 mm
(0.025 inch). Use a depth gauge tool for checking the
depth gauge clearances.
■ Every time the chain is filed, check the depth gauge
clearance.
■ Use a flat file (not provided) and a depth gauge jointer
(not provided) to lower all gauges uniformly. Use a 0.6
mm (0.025 inch) 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 file.
■ Depth gauges must be adjusted with the flat file in the
same direction the adjoining cutter was filed with the
round file. Use care not to contact cutter face with flat
file when adjusting depth gauges.
MAINTAINING THE GUIDE BAR
See figure 57.
WARNING
Check that the switch is in the STOP "O" position before
you work on the saw.
English (Original instructions)
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 file as soon as they occur.
A bar with any of the following faults should be replaced:
■ Wear inside the bar rails which permits the chain to lie
■ Bent guide bar
■ Cracked or broken rails
■ Spread rails
In addition, lubricate guide bars (with a sprocket at their
tip) weekly. 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.
CLEANING THE AIR FILTER
See figure 58 - 59.
■ Activate chain brake.
■ Remove the two screws holding the engine cover.
■ Lift the front of the engine cover past chain brake lever.
■ Lift the back of the engine cover past the handle.
■ Before removing the air filter from the carburettor, blow
■ Lift the air filter off the air filter base.
Choose one of the following cleaning options:
■ To lightly clean, tap the filter against a smooth, flat
■ For a more thorough cleaning, clean in warm soapy
NOTE: An alternative method is to clean the filter with
compressed air (always wear eye protection to avoid eye
injury).
NOTE: If you use an air hose for drying, blow through both
sides of filter.
Make sure the air filter is correctly placed in the air filter
cover before reassembly. Never run the engine without
the air filter, serious damage could result.
