HOW THE PULLZALL WORKS
HOW THE PULLZALL WORKS
How the PullzAll Reacts to Load The PullzAll is rated by pulling capacity. The maximum pulling torque occurs when there is only one layer of wire rope on the drum. As the layers of wire rope on the drum increase, the pulling power decreases. This is the basics of mechanical advantage.
PullzAll Mechanics
Before using your WARN PullzAll to pull or lift a load it is important to understand how it works. The major advantage of the PullzAll is its handheld convenience for performing numerous recreational and work tasks. Thinking through how you intend to use your PullzAll now could save you a big headache later. Control of Your PullzAll The PullzAll tool has an On/ Off power switch and is controlled by a directional switch and a variable speed trigger control. The directional switch provides control of the forward and reverse rotation of the spooling drum. Keep tension on the wire rope when winding in or out to prevent “bird nesting” that can bind and entangle the wire rope causing damage to it and the PullzAll. When you see the red paint on the wire rope, do not spool out any further. Doing so, can cause the wire rope to spool on the drum in the wrong direction. This can damage the wire rope and fairlead. The direction selection arrow should always match the direction of the wire rope when it is spooling in or out.
It is important to understand that the longer the pull, the more heat gets created within the motor. Spooling out the rope also generates heat. Let the motor cool between pulls because prolonged use without cooling the PullzAll will damage the motor. Run Time/Duty Cycle The PullzAll is rated for intermittent duty. It should not be operated for long periods with the motor at low RPMs. When the motor approaches stall speed a very rapid heat build up occurs which may cause motor damage. Follow the recommended run times and cooling times in the table shown. If the unit does not function after it is allowed to cool, call a Warn authorized service center.
WARNING Always keep PullzAll and pulling load in sight during pulling operation.
RUN TIME/DUTY CYCLE TABLE LOAD 500 lbs. (227 kg) 1000 lbs. (454 kg) RUN TIME 2 min 1 min COOL TIME 30 min 30 min
WARNING
Never spool out past the red paint on wire rope.
Load Limiter
Exceeding the PullzAll capacity will cause the load limiter to trip, which interrupts the power to the motor. This prevents overheating and potential motor damage. At 90% of pulling capacity the overload indicator turns red. When 100% of pulling capacity is reached the load limiter will cause the overload indicator to fl ash red and the PullzAll motor to stop. When this occurs, release the load by spooling out. Do not attempt to apply the same load if the load limiter has tripped, as this can be harmful to the unit. If the load limiter fails to reset contact an authorized service center. If the load limiter continues to trip, perform the following actions: 1) Reduce the weight of the load. 2) Increase the distance of the anchor point. 3) Rig a double line pull. For details: See “Rigging Techniques” section in this manual.
NOTICE
The PullzAll is controlled
by the variale speed trgger and direction selection switch.
The variable speed trigger switch has two general modes of operation: 1) Variable speed mode for fi ne load positioning. 2) Full speed mode for long distance.
