SPECIFIC SAFETY INSTRUCTIONS
WARNING! TWO HANDED OPERATION REQUIRED
This machine requires the use of two hands to ensure safe
operation and should not be used when working from ladders
and step ladders.
If the machine is to be used when working at height a suitable,
stable platform or scaffold tower with hand rails and kick boards
should be used.
WARNING!
Some wood and wood type products especially MDF (Medium
Density Fibreboard) can produce dust that can be hazardous to
your health. We recommend the use of an approved face mask
with replaceable filters when using this machine in addition to
using the dust extraction facility.
DANGER
a) Keep hands away from cutting area and blade. Keep your
second hand on auxiliary handle, or motor housing. If both
hands are holding the saw, they cannot be cut by the blade.
b) Do not reach underneath the workpiece. The guard cannot
protect you from the blade below the workpiece.
c) Adjust the cutting depth to the thickness of the workpiece.
Less than a full tooth of the blade teeth should be visible
below the workpiece.
d) Never hold the piece being cut in your hands or across your
leg. Secure the workpiece to a stable platform. It is important
to support the work properly to minimize body exposure,
blade binding, or loss of control.
e) Hold the power tool by insulated gripping surfaces when
performing an operation where the cutting tool may contact
hidden wiring or its own cord. Contact with a "live" wire will
also make exposed metal parts of the power tool "live" and
shock the operator.
f) When ripping, always use a rip fence or straight edge guide.
This improves the accuracy of cut and reduces the chance of
the blade binding.
g) Always use blades with correct size and shape (diamond
versus round) of arbour holes. Blades that do not match the
mounting hardware of the saw will run eccentrically, causing
loss of control.
h) Never use damaged or incorrect blade washers or bolt. The
blade washers and bolt were specially designed for your
saw, for optimum performance and safety of operation.
CAUSES AND OPERATOR PREVENTION OF
KICKBACK
• Kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to lift up
and out of the workpiece toward the operator.
• When the blade is pinched or bound tightly by the kerf closing
down, the blade stalls and the motor reaction drives the unit
rapidly back toward the operator.
• If the blade becomes twisted or misaligned in the cut, the
teeth at the back edge of the blade can dig into the top
surface of the wood causing the blade to climb out of the kerf
and jump back toward operator.
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below.
a) Maintain a firm grip with both hands on the saw and position
your arms to resist kickback forces. Position your body to
either side of the blade, but not in line with the blade. Kickback
could cause the saw to jump backwards, but kickback forces
can be controlled by the operator, if proper precautions are
taken.
b) When blade is binding, or when interrupting a cut for any
reason, release the trigger and hold the saw motionless in
the material until the blade comes to a complete stop. Never
attempt to remove the saw from the work or pull the saw
backward while the blade is in motion or kickback may occur.
Investigate and take corrective actions to eliminate the cause
of blade binding.
c) When restarting a saw in the workpiece, centre the saw blade
in the kerf and check that the saw teeth are not engaged into
the material. if saw blade is binding, it may walk up or kick
back from the workpiece as the saw is restarted.
d) Support large panels to minimise the risk of blade pinching
and kickback. Large panels tend to sag under their own
weight. Supports must be placed under the panel on both
sides, near the line of cut and near the edge of the panel.
e) Do not use dull or damaged blades. Unsharpened or
improperly set blades produce a narrow kerf causing
excessive friction, blade binding and kickback.
f) Blade depth and bevel adjusting locking levers must be tight
and secure before making a cut. If blade adjustment shifts
while cutting, it may cause binding and kickback.
g) Use extra caution when making a "plunge cut " into existing
walls or other blind areas. The protruding blade may cut
objects that can cause kickback.
SAFETY INSTRUCTIONS REGARDING LOWER
GUARD
a) Check lower guard for proper closing before each use. Do
not operate the saw if the lower guard does not move freely
and close instantly. Never clamp or tie the lower guard in the
open position. If the saw is accidentally dropped, lower guard
may be bent. Raise the lower guard with the blade guard
lever and make sure it moves freely and does not touch the
blade or any other part, in all angles and depths of cut.
b) Check the operation of the lower guard spring. If the guard
and the spring are not operating properly, they must be
serviced before use. Lower guard may operate sluggishly
due to damaged parts, gummy deposits, or a build-up of
debris.
c) Lower guard should be retracted manually only for special
cuts such as "plunge cuts" and "compound cuts". Raise
lower guard by blade guard lever. As soon as blade enters
the material, the lower guard must be released. For all other
sawing tasks, the lower guard should operate automatically.
d) Always observe that the lower guard is covering the
blade before placing the saw down on bench or floor. An
