OPERATION (cont.)
11
Caution:
During operation, it is important not to overload the sharpener. The
sharpener should run at almost full speed at all times. If too much pressure is applied,
the sharpener will start to slow down (noticed mainly by the dramatic audible change
of the motor.
Should the sharpener speed slow down, allow the hand-piece (1) to raise up a little
(in effect allowing the disc to lift away from the chain) and let the motor return to full
speed before continuing to sharpen.
The chain saw chain is fitted with two sets of teeth, usually every second tooth is the
opposite to the last. When there is an odd number of teeth in the chain, the teeth
can be doubled up ie. left, left, right.
Should the chain have an odd number of teeth, check to find this point, and be
aware of this condition.
The sharpening process consists of two operations. These are, setting to the left, and
then setting the right. It is suggested to sharpen all of the teeth that face one side
(every second tooth) and then proceeding to sharpen all the teeth on the opposite side.
It is important to always ensure the tooth is correctly located against the chain stop,
the chain is correctly locked in place, the initial set-up as previously described has
been correctly carried out, and the correct safety gear is being worn.
With the chain correctly aligned against the chain stop and the depth stop set (refer
to Setting instructions prior to the operation), start the tool whilst standing to one
side of the grinding disc and allow the motor to run for several seconds (allowing the
motor to get up to full speed).
Check the above settings by carefully lowering the grinding disc down the face of the
tooth until the hand-piece (1) comes to a stop.
As the grinding disc passes down the face of the tooth, it should be a light even pass.
DO NOT attempt to try and make a heavy pass. It should be a very light “brush” of
the front face of the tooth. If the cut is too heavy, stop and allow the hand-piece (1)
to rise back up, and turn the tool off. If the pass was too heavy, adjust the chain stop
adjusting knob (15) in an anti-clockwise direction slightly (suggest no more than 1/8
of a turn). Then tighten the chain stop adjusting knob lock nut (14).
Once sharpening of the tooth completed, rotate the guide clamp lever (13) fully to the left
to un-lock the chain clamp (sliding guide).
Slide the chain to the right, allowing the chain stop to ride over the links and teeth
until the next tooth (orientated the same as the first tooth) rides under the stop.
When the tooth slides under the chain stop, gently slide the chain to the left so the
stop engages and locates the tooth.
With the rear of the tooth firmly located, lock the clamping lever, and repeat the
cutting test. If the grinding disc is not grinding sufficient off the face of the tooth,
repeat the above adjustment but rotate the chain stop adjustment knob (15) clockwise.
Lower the hand-piece (in effect lowering the disc) fully until the disc reaches the
bottom of the tooth. Check to ensure the grinding disc has not cut into the chain link.
If the grinding disc touches the chain link, re-set the stop by adjusting the depth of
grind knob (3) in a clock wise direction (suggest 1/8 turn at a time). Re-test after
each adjustment.
