Force Gauge

The Model 88 Cable Puller is equipped with an integral force gauge. 
To calibrate the force gauge, run the puller for 1 minute with no load. 
While the puller is running, use adjustment screw on face of force 
gauge to set needle to zero pounds of force. The operator should 
always monitor the force gauge throughout the entire cable pull. 
The force gauge has 3 color sections to help you identify operating 
conditions. These sections are:

Color

Condition

Green

Puller can be run continuously

Yellow

50% duty cycle; 15 minutes on / 15 minutes off

Red

Overload Condition – Do NOT operate puller
Correct overload condition or set up a tandem pull
(See page 29. ) 

Mounting Chain Installation

The Model 88 Cable Puller is designed to be mounted using the two mount-
ing chains provided. The handles on the chains should provide sufficient
leverage to tighten the chains securely. No other tools are needed. Be sure
to check the mounting chains for kinks and twists before you tighten them.

figure 31 

A– Loosen the mounting chain 

handle so that only 3 or 4 threads
remain engaged.

B– Wrap the chain around the 8092 Puller

Mount, 8045 floor mount, conduit or
structural support which are capable
of handling the pulling forces.

C– Pull the loose end of the mounting

chain tight and hook the closest 
chain link into the recessed area.

D– Tighten the chain handle.

Repeat this process for second 
mounting chain.

Be sure threads do not bottom out before chain becomes tight.
