Cutting sequence
First make the lower horizontal cut. Now make the two vertical
cuts. Finish with the upper horizontal cut.
Remember to divide the blocks up into manageable pieces so
that they can be transported and lifted safely.
CAUTION! If the upper horizontal cut is made before the
lower horizontal cut, the work piece will fall on the blade and
jam it.
How to avoid kickback
WARNING! Kickback can happen very
!
suddenly and violently; kicking the power
cutter and cutting blade back at the user. If
this happens when the cutting blade is
moving it can cause very serious, even fatal
injuries. It is vital you understand what
causes kickback and that you can avoid it by
taking care and using the right working
technique.
What is kickback?
The word kickback is used to describe the sudden reaction
that causes the power cutter and cutting blade to be thrown
from an object when the upper quadrant of the blade, known
as the kickback zone, touches an object.
Kickback only occurs when the cutting blades kickback zone
touches an object.
SAFETY INSTRUCTIONS
General rules
• Never start to cut with the upper quadrant of the blade as
shown in the figure, also known as the kickback zone.
• Keep a good balance and a firm foothold.
• Always hold the machine in a firm grip with both hands.
Hold it so that the thumbs and fingers grip round the
handles.
• Stand at a comfortable distance from the work piece.
• Always cut at maximum speed.
• Take care when inserting the blade in an existing cut.
• Never cut above shoulder height.
• Be alert to movement of the work piece or anything else
that can occur, which could cause the cut to close and
pinch the blade.
Pull in
Pull in occurs when the disc's lower section suddenly stops or
when the cut closes. (To avoid, see the heading "Basic rules"
and "Jamming/rotation", here below.)
Pinching/rotation
If the cut is pressed together this can lead to jamming. The
machine can be pulled down suddenly with a very powerful
jerk.
How to avoid pinching
Support the work piece in such a way that the cut remains
open during the cutting operation and when the cut is
finished.
Check the engine speed
Use a revolution counter regularly to check the engine speed
at the working temperature, at full throttle and without a load.
WARNING! The unit must be adjusted at an
!
authorised service workshop before it may
be used, if the speed is higher than that
stated.
