WARNING:

 Chain breakage can result in high-speed ejection of parts, 

which can result in death or serious personal injury to operators or 

bystanders. The items listed below are critical to minimizing the risk of 

chain breakage and injury.

5.4 

DO NOT operate a diamond chain saw with damaged, modi-

fied, broken, or missing side cover, bottom guard flap. The side cover, 

bottom guard, and guard flap provide protection against contact with 

moving parts, ejected debris, broken chain, thrown water and concrete 

slurry.

5.5 

DO NOT operate a saw with loose, missing, damaged, or im-

properly repaired parts.

5.6 

DO NOT install or run the chain backwards. The bumper must

lead the segment into the cut.  (Applies to concrete chains only.)

SAFETY

   WARNING

THE FOLLOWING SYMBOL APPLIES TO ALL THE ITEMS LISTED ON THIS PAGE 

A potentially hazardous situation exists which, if not avoided, 

could result in death or serious injury. 

Chain breakage can result in high-speed ejection of parts, which can result in death or 

serious personal injury to operators or bystanders. The items listed below are critical to 

minimizing the risk of chain breakage and injury. 

•  DO NOT operate a diamond chainsaw with a damaged, modified, broken, or missing side 

cover, bottom guard, or guard flap. The side cover, bottom guard, and guard flap provides 

protection against contact with moving parts, ejected debris, broken diamond chain, 

thrown water and concrete slurry. 

•  DO NOT operate a saw with loose, missing, damaged or improperly repaired parts.
•  DO NOT install or run the chain backwards. The bumper must lead the segment into

 

the cut.

•  DO NOT insert a diamond chainsaw into a slot narrower than the chain segments. Rapid 

pushback might occur. Reference: Most diamond segments are .225 inches (5.72 mm) 

wide. 

•  DO NOT use damaged, modified or improperly repaired chain. 
•  DO NOT run a diamond chainsaw upside-down. Concrete debris can fly back into the 

operator’s face. 

•  NEVER cut ductile iron pipe with the saw (except when using PowerGrit

TM

 Cutting 

System). Segment loss or diamond chain breakage may occur. 

•  See page 16 for information about cutting ductile iron pipe with PowerGrit

TM

.

5.7 

DO NOT insert a diamond chain saw into a slot narrower than the 

chain segments. Rapid push back might occur. Reference: Most diamond 

segments are .225 inches (5.72 mm) wide.

5.8 

DO NOT use damaged, modified or improperly repaired chain.

5.9 

DO NOT run a diamond chain saw upside-down. Concrete debris 

can fly back into the operator’s face.

5.10 

DO NOT cut ductile iron pipe with concrete chain. Segment loss or 

diamond chain breakage may occur.

5.11 

DO NOT cut concrete with ductile iron chain. Segment loss or 

diamond chain breakage may occur.

Verify  all  machine guards are  in  good condition and will function properly before  using  the  machine. 

Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any 

other conditions that may affect machine operation. A guard, power switch or other part that is damaged 

should be properly repaired or replaced by an authorized service center unless indicated elsewhere in 

this instruction manual. Do not operate machine if lever or engine on/off switch does not function 

properly.
