Instruction & User Manual

should be no nails or foreign objects in 
the workpiece.

–

Small debris or loose pieces of wood 

–

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.

guard or be thrown by the spinning 
blade.

or other objects that contact the 
revolving blade can be thrown with 
high speed. 

8 

Do not use the saw until the table 
is clear of all tools, wood scraps, 
etc., except for the workpiece.

–

Stacked multiple workpieces cannot 
be adequately clamped or braced and 
may bind on the blade or shift during 
cutting.

–

A level and firm work surface reduces 
the risk of the mitre saw becoming 
unstable.

9

Cut only one workpiece at a time.

10

Ensure the mitre saw is mounted 

13

Do not use another person as a 
substitute for a table extension or 
as additional support.

–

If confined, i.e. using length stops, 
the cut-off piece could get wedged 
against the blade and thrown 
violently.

14

The cut-off piece must not be 
jammed or pressed by any means 
against the spinning saw blade.

–

Rods have a tendency to roll while 
being cut, causing the blade to “bite” 
and pull the work with your hand into 
the blade.

15

Always use a clamp or a fixture 
designed to properly support round 
material such as rods or tubing.

–

This will reduce the risk of the 
workpiece being thrown.

16

Let the blade reach full speed before 
contacting the workpiece.

–

Continued sawing with a jammed 
workpiece could cause loss of control 
or damage to the mitre saw.

17

If the workpiece or blade becomes 
jammed, turn the mitre saw off. Wait 
for all moving parts to stop and 
disconnect the plug from the power 
source and/or remove the battery 
pack. Then work to free the jammed 
material. 

18

After finishing the cut, release the 
switch, hold the saw head down and 
wait for the blade to stop before

or placed on a level, firm work 
surface before use.

–

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 

–

 Workpieces longer or wider than the 
mitre saw table can tip if not securely 
supported. If the cut-off piece or 
workpiece tips, it can lift the lower 

the fence.

11

Plan your work. Every time you 

12

Provide adequate support such as 
table extensions, saw horses, etc. 
for a workpiece that is wider or 
longer than the table top.

change the bevel or mitre 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.
