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.
Diamond 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 diamond 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 saw with loose, missing damaged or improperly repaired parts.
• DO NOT exceed the hydraulic flow for your saw model: 8 gpm (30 lpm) or 12 gpm (45 lpm)
at 2,500 psi (172.5 bar) hydraulic pressure.
• DO NOT install or run the chain backwards. The bumper should lead the segment into the
cut.
• DO NOT run the saw backwards. The chain should travel away from the operator on the
top of the bar and return on the bottom of the bar.
• DO NOT insert the diamond chainsaw into a slot narrower than the chain segments.
Rapid pushback might occur. Ref: Most diamond segements are .225 (5.72 mm) wide.
• DO NOT use the 853PRO side cover as a replacement cover for another saw.
• DO NOT run the saw upside-down. Concrete debris can fly back into the operator’s face.
• NEVER cut ductile iron pipe with the saw. Segment loss or diamond chain breakage may
occur.
• DO NOT use your hands to search for hydraulic leaks. Hydraulic fluid escaping under
pressure can penetrate skin. If any hydraulic flud is injected into skin seek medical
attention immediately.
