Checking The Lubrication System
To check that the lubrication system is working, run the
chainsaw while holding the guide bar above some
paper. A steadily increasing stain caused by oil spray
shows that the lubrication system is working. If there is
no oil stain check and clean the lubrication system
before using the chainsaw. The chainsaw must never
be run without the oilier in full working condition.
The Cutting Chain Brake
The chainsaw is fitted with a cutting chain brake
mechanism, that will stop the cutting chain within
1/10th of a second. If the hand protection guard
(cutting chain brake) is brought into the tripping
position either manually or while operating the
chainsaw as a result of a kickback by the back of the
operators hand or if the chainsaw is switched off by
releasing the ON/OFF switch.
Connecting To The Mains Supply. (Pic.8)
Starting And Stopping
Remove the chain guard. Connect the mains supply
lead to a suitable mains supply socket via a residual
current device (RCD). Set the cutting chain brake lever
to the released position by pulling the hand protection
guard towards the front handle (Pic.8) (8.1) it should
click into position. Press in the safety button on the
side of the rear handle and squeeze the trigger switch.
The saw should now run. To stop the saw release the
trigger switch.
Checking The Cutting Chain Brake On/Off
Switch.
warning! The chainsaw must not be operated if the
cutting chain brake fails to operate.
Start the chainsaw, now release the trigger, the cutting
chain brake should stop the cutting chain immediately.
The motor will run down slowly.
Checking The Cutting Chain Brake Lever
Operation
warning! The chainsaw must not be operated if the
cutting chain brake fails to operate.
Start the chainsaw, now knock the hand protection
guard forwards (Pic.8) (8.2) the cutting chain brake
should stop the cutting chain immediately. The motor
will run down slowly when the ON/OFF trigger is
released.
Running In The Cutting Chain
Before using the chainsaw from new or after fitting a
new cutting chain the cutting chain must be ‘run in’.
After following the above procedures, allow the
chainsaw to run for between 2 to 3 minutes during this
time ensure that the cutting chain is being lubricated
correctly. When the running in period has been
completed check the cutting chain tension and re-
tension if required.
Nose Guard
One of the most common causes of injury from a
chainsaw is caused by ‘kickback’. Kickback is caused
when the nose of the guide bar contacts an object
while the cutting chain is moving. A single saw tooth
essentially jams into an object and instead of cutting it
, the energy from the saw is redirected backwards and
upwards. This causes the saw to (kickback) in your
hands, which can result in severe injury.
The nose guard fitted to this chainsaw is designed to
cover the nose area of the cutting chain reducing the
possibility of kickback. Unfortunately the fitting of the
nose guard limits the cutting capacity of the chainsaw,
(refer to technical specification).
Cutting Chain Sharpening
It is not recommended that the occasional user
attempts to sharpen a chainsaw cutting chain.
Chainsaw cutting chains should only be sharpened by
an experienced competent person, it is safer to fit a
new cutting chain. If the Cutting chain tends to move
sideways during cutting or the cut produces fine dust
instead chips, or if heavy pressure is required to keep
cutting or if there is a smell of burning wood the saw
cutting chain requires sharpening.
warning! Always ensure that the chainsaw is
disconnected from the mains supply before carrying
out any maintenance, cleaning, cutting chain
sharpening, cutting chain replacement or any
adjustments.
