FAILURE TO HEED THE FOLLOWING WARNINGS
MAY RESULT IN SERIOUS INJURY OR DEATH!
•Do not use to lift or move people. If your task involves
moving or lifting people, you must use the proper
equipment, not this winch.
•Winch operators must be trained in the proper, safe
operation of the winch.
•Cable anchors on Tulsa Winches are not designed to
hold the rated load of the winch. You must keep at least
five (5) wraps of cable on the drum to insure that the
cable doesn’t come loose.
•Stay clear of suspended loads and of cable under
tension. A broken cable or dropped load can cause
serious injury or death.
•Make sure that all equipment, including the winch and
cable, is maintained properly. Pay especially close
attention to the clutch, making sure that it fully engages
when shifted. Do not attempt to disengage the clutch
when a load is on the winch.
•Avoid shock loads. This type of load imposes a strain
on the winch many times the actual weight of the load
and can cause failure of the cable or of the winch.

INTRODUCTION
Thank you for purchasing a new Tulsa Winch. We are proud of
our products and are certain that they will perform your winch
tasks properly. However, we do ask that you take a few minutes
to read and thoroughly understand this booklet. Also, if you have
new operators assigned to the winch, make sure that they read
and understand it. Because of the large number of models we
manufacture, we are unable to show parts lists for every model
in this booklet. If you want or need parts lists, please write Tulsa
Winch, 11135 S. James, Jenks, OK 74037. Or call (918) 298-
8300 or fax us at [phone]. You may also go to our Web

GENERAL OPERATION
1. Be sure to read all safety instructions thoroughly. It is
important that each operator is aware of the consequences
of misuse or poor operating practices of this winch.
2. Tulsa Winch products are not to be used to lift, hoist, or
move people. If your application requires moving persons,
you must use the proper equipment for the task.
3. Cable anchors on Tulsa Winch products are not designed to
hold the rated load of the winch. You must keep at least five
(5) wraps of cable on the drum to insure that the cable does
not come loose.
4. Personnel must stay clear of a suspended load or any line
under load. A distance of 1-1/2 times the length of the cable
should be maintained while the cable is under tension.
Failure to heed this warning may result in serious injury or
death.
5. Make sure that all equipment is maintained properly and
regular systems checks are performed to insure your winch
is working safely. Refer to the maintenance section of this
manual for details on these procedures.
6. Avoid shock loads. This type of load imposes a strain on the
winch many times the actual weight of the load and can
cause failure of the cable or of the winch.
7. Always inspect cable before beginning job. Never allow
cable to slide through hands while maintaining tension, use
hand-over-hand method to keep cable tension while
spooling. Always use leather gloves when handling cable.

THEORY OF OPERATION
1. The Tulsa Planetary Winches are composed of an input from
either a high torque, low speed geroler motor or a high-
speed gear or piston motor. Input drives through a multiple
disc brake that is spring applied and hydraulically released,
and then through planet gear sets to the cable drum.
2. During inhaul, the brake is not released since the load is
driven through a one-way cam clutch, bypassing the brake.
When the load comes to a stop, the cam clutch locks up and
the load is prevented from moving by the brake.
3. During payout, a brake valve is used to prevent the load
from moving faster than desired. This brake valve partially
blocks the main line from the motor back to the directional
control valve, allowing only a limited amount of oil through
the motor. Also, any time there is sufficient pressure to
modulate the brake valve, this same pressure releases the
multiple disc brake.
USING A SNATCH BLOCK
By using a snatch block you have effectively cut the load on the
winch in half. A snatch block should be used any time you have
a concern about the ability of the winch or cable to move a load.
The following illustration shows one way to rig such a block.
