STOPPER BOLT ADJUSTMENT

THE STOPPER BOLT IS PROBABLY THE MOST 

IMPORTANT PART OF YOUR PORTABLE CUTTER...

CUTTING

The adjustable stopper functions to maintain the rebar in 

the correct position during cutting and must be properly 

set for each size of rebar before use.

1. Screw in stopper to provide sufficient clearance for re-

bar.

2. Insert rebar fully into U-shaped support. Make sure 

that rebar is resting on the base of the support.

3. Keeping rebar at right angles (90 degrees) to front cut-

ter block, screw out stopper until it is just touching the 

rebar. Once set, the stopper needs no further adjustment 

while cutting rebar of the same diameter, but must be re-

set for a different size rebar.

CAUTION: Failure to correctly set the stopper bolt will 

result in excessive wear of cutter blocks and may cause 

cut end to fly out. This will also lead to piston and cylinder 

damage.

BENDING

1. Screw in stopper bolt to provife sufficient clearance for 

rebar.

2. Place rebar between the bending rollers (small moving 

roller and the larger fixed roller.)

3. Adjust the stopper bolt to keep the rebar at a right angle 

(90 degrees) to bending rollers.

POINTS OF ATTENTION

1. Be especially careful when cutting off short lengths 

(30cm/12” or less) as the cut 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 or operate the tool on dirt – use 

a plywood base under the rebar cutter to keep armature 

and fan clean

CARE: If the vents are covered, the motor will overheat 

and may burn out.

3. If hydraulic oil exceeds 70 degrees C (158 degrees 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 observed and motor is unusually 

hot, check carbon-brushes.  (See maintenance)

5. If piston should ever fail to retract completely, push rear 

cutter block backwards to manually retract piston or check 

under piston to remove and debris keeping the piston from 

retracting.  

CAUTION: Use a rebar or flat metal bar for this purpose. 

Never push cutter block with any part of the hand, even if 

gloved. 

GENERAL MAINTENENCE

CUTTER BLOCK MAINTENANCE

Before using, always check that the two bolts on each cut-

ter block are properly tightened. Using a loose block will 

result in damage to block and housing. Also check con-

dition 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 your tool 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. 

Disconnect the unit. Wipe or brush away all dirt and metal 

filings. Pay particular attention to the lower half of the pis-

ton, where dirt is more easily accumulated.

NEVER USE YOUR CUTTER TO CUT REBAR IN WET 

CONCRETE.

OIL-LEVEL CHECK

As the cutters are hydraulically operated, the oil-level must 

be checked at frequent intervals, preferably every day. Fail-

ure to maintain the oil at the proper level results in a drop 

in pressure and loss of cutting power.
