Cutting
1. Be especially careful when cutting off short lengths (12 inches or less) as the but end tends to
fly out.
CAUTION:
Flying ends are a hazard to all personnel in the vicinity. Erect safety screens.
2. Do not cover air vents.
If the events are covered, motor will overheat and may burn out.
3. If hydraulic oil exceeds 158
°
F in temperature, power will drop.
Allow unit to cool before resuming operation. (Be particularly careful in summer, when the
aluminum pump case heats up quicker.)
4. If a drop in power is noticed and the motor is unusually hot, check carbon brushes.
5. If piston should ever fail to retract completely, push rear cutter block backwards to manually
retract piston.
CAUTION:
Use a rebar or flat metal bar for this purpose. Never push cutter block with any
part of the hand, even if gloved.
Once piston has been retracted, pull trigger-switch long enough to partially advance piston. Unplug
unit. Check piston and housing for accumulated dirt and iron filings that maybe jamming the piston.
If, after cleaning, piston still does not automatically retract when fully extended, the piston itself may
be damaged. Return the unit to an authorized service center for repair.
MAINTENANCE
Cutter Blocks
Before using, always check that the two bolts on each cutter block are properly tightened. Operating
with a loose block will result in damage to block and housing. Also check condition of cutter blocks.
If either cutting edge is dull or chipped, remove retaining bolts and rotate both blocks so that two
new edges come into use. Replace and tighten bolts (each block has four cutting edges). When all
four cutting edges have been used or if either block is cracked or otherwise damaged, replace both
blocks.
CAUTION:
A loose or cracked block may result in injury to operator.
Cleaning
Clean cutter every day, preferably immediately after use.
CAUTION:
Wear gloves to protect hands from metal splinters. Do not use an air-gun
—
blasting with air can cause metal filings and/or dust to get into eyes and respiratory system.
1. Disconnect unit.
