SPECIFIC SAFETY RULES
Flooring saws are intended to cut wood or wood-like
products, they cannot be used with abrasive cut-off
wheels for cutting ferrous material such as bars, rods,
studs, etc.
Abrasive dust causes moving parts such as
the guard to jam. Sparks from abrasive cutting will burn
the guard, the kerf insert and other plastic parts.
Do not use the saw until the table is clear of all tools,
wood scraps, etc., except for the workpiece.
Small de-
bris or loose pieces of wood or other objects that contact
the revolving blade can be thrown with high speed.
Cut only one workpiece at a time.
Stacked multiple
workpieces cannot be adequately clamped or braced
and may bind on the blade or shift during cutting.
Ensure the flooring saw is mounted or placed on a
level, firm work surface before use.
A level and firm
work surface reduces the risk of the flooring saw becom-
ing unstable.
Use the saw on the floor or a secure table to ensure
adequate support
.
Do not use another person as a substitute for a table
extension or as additional support.
Unstable support
for the workpiece can cause the blade to bind or the
workpiece to shift during the cutting operation pulling
you and the helper into the spinning blade.
Let the blade reach full speed before contacting the
workpiece.
This will reduce the risk of the workpiece
being thrown.
If the workpiece or blade becomes jammed, turn the
flooring saw off. Wait for all moving parts to stop and
disconnect the plug from the power source and/or re-
move the battery pack. Then work to free the jammed
material.
Continued sawing with a jammed workpiece
could cause loss of control or damage to the flooring saw.
Save these instructions.
Refer to them frequently and
use to instruct other users. If you loan someone this tool,
loan them these instructions also.
FOR RIP CUTS
Never cross your hand over the intended line of cut-
ting either in front or behind the saw blade.
Supporting
the workpiece ”cross handed” i.e. holding the workpiece
to the right of the saw blade with your left hand or vice
versa is very dangerous.
Do not reach behind the fence with either hand closer
than 4 in. (100 mm) from either side of the saw blade,
to remove wood scraps, or for any other reason while
the blade is spinning.
The proximity of the spinning saw
blade to your hand may not be obvious and you may be
seriously injured.
After finishing the cut, release the switch and wait for
the blade to stop before removing the cut-off piece.
Reaching with your hand near the coasting blade is dan-
gerous.
Make sure the flooring saw is locked during rip cutting
and fences are locked in place before cutting.
FOR CROSS CUTS
Use clamps to support the workpiece whenever pos-
sible. If supporting the workpiece by hand, you must
always keep your hand at least 4 in. (100 mm) from
either side of the saw blade. Do not use this saw to
cut pieces that are too small to be securely clamped
or held by hand.
If your hand is placed too close to the
saw blade, there is an increased risk of injury from blade
contact.
Plan your work. Every time you change the bevel or
miter angle setting, make sure the adjustable fence
is set correctly to support the workpiece and will not
interfere with the blade or the guarding system.
With-
out turning the tool ”ON” and with no workpiece on the
table, move the saw blade through a complete simulated
cut to assure there will be no interference or danger of
cutting the fence.
The cut-off piece must not be jammed or pressed by
any means against the spinning saw blade.
If confined,
i.e. using length stops, the cut-off piece could get wedged
against the blade and thrown violently.
The workpiece must be stationary and clamped or
held against both the fence and the table. Do not feed
the workpiece into the blade or cut ”freehand” in any
way.
Unrestrained or moving workpieces could be thrown
at high speeds, causing injury.
Inspect your workpiece before cutting. If the
workpiece is bowed or warped, clamp it with the
outside bowed face toward the fence. Always make
certain that there is no gap between the workpiece,
fence and table along the line of the cut.
Bent or warped
workpieces can twist or shift and may cause binding on
the spinning saw blade while cutting. There should be no
nails or foreign objects in the workpiece.
Always use a clamp or a fixture designed to properly
support round material such as rods or tubing.
Rods
have a tendency to roll while being cut, causing the blade
to bite and pull the work with your hand into the blade.
Push the saw through the workpiece. Do not pull the
saw through the workpiece. To make a cut, start the
saw and push the saw through the workpiece.
Cut-
ting on the pull stroke is likely to cause the saw blade
to climb on top of the workpiece and violently throw the
blade assembly towards the operator.
