SAFETY INSTRUCTIONS FOR MITER SAWS
d. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool . Power tools are dangerous in the hands of untrained users .
e. Maintain power tools and accessories . Check for misalignment or binding of moving parts, breakage of
parts and any other condition that may affect the power tool’s operation . If damaged, have the power
tool repaired before use . Many accidents are caused by poorly maintained power tools .
f. Keep cutting tools sharp and clean
.
Properly maintained cutting tools with sharp cutting edges are less likely to
bind and are easier to control .
g. Use the power tool, accessories and tools bits etc . in accordance with these instructions, taking into
account the working conditions and the work to be performed . Use of the power tool for operations different
from those intended could result in a hazardous situation .
h. Keep Handles and grasping surfaces dry, clean and free from oil and grease . Slippery handles and grasping
surfaces do not allow for safe handling and control of the tool in unexpected situations .

Service
a. Have your power tool serviced by a qualified repair person using only identical replacement parts . This
will ensure that the safety of the power tool is maintained .
1.
a. Miter 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 lower guard to jam . Sparks from abrasive cutting will burn the lower guard, the kerf insert and other plastic parts .
b. Use clamps to support the workpiece whenever possible . If supporting the workplace by hand, you must
always keep your hand at least 100mm 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 .
c. 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 .
d. Push the saw through the workpiece
. Do not pull the saw through the workpiece . To make a cut, raise
the saw head and pull it out over the workpiece without cutting, start the motor, press the saw head
down and push the saw through the workpiece .
Cutting 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 .
e. Never cross your hand over the intended line of cutting 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 .
f. Do not reach behind the fence with either hand closer than 100mm 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 .
g. 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 .
h. Do not use the saw until the table is clear of all tools, wood scraps, etc . , except for the workpiece . Small
debris or loose pieces of wood or other objects that contact the revolving blade can be thrown with high speed .
i. 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 .
j.
Ensure the miter saw is mounted or placed on a level, firm work surface before use .
A level and firm work
surface reduces the risk of the miter saw becoming unstable .
k. 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.
Without 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.
