SAFETy INSTRUCTIONS

20 . 

DO NOT use dull or damaged blades. 

Bent blades can break easily or cause 
kickback .
21 . 

NEVER hold a work piece by hand if it 

is too small to be clamped. ALWAyS

 keep 

your hands clear of the “no hands” zone .
22 . 

NEVER apply lubricants to the blade 

when it is running. 

23 . 

NEVER use solvents to clean plastic 

parts.

 Solvents could dissolve or otherwise 

damage the material .
24 . 

DO NOT turn the motor switch on and 

off rapidly.

 This could cause the blade to 

loosen, which could create a hazard . Should 
this ever occur, stand clear and allow the 
saw blade to come to a complete stop . 
Disconnect the saw from the power source, 
and securely tighten the blade bolt .
25 . 

NEVER leave the saw unattended 

while 

connected to a power supply .
26 . 

kEEP THE MOTOR AIR SLOTS 

clean 

and free of chips or dust . To avoid motor 
damage, the motor should be blown with 
air or vacuumed frequently to keep sawdust 
from interfering with the motor ventilation .
27 . 

NEVER lift this tool by gripping the 

cutting handle or by the fence.

 This may 

cause misalignment . 

ALWAyS

 lock the saw 

arm in the 

“DOWN”

 position and then carry 

the saw by holding the base or lift it by the 
carrying handle/support bracket .
