1.  Be certain equipment (boom, sheave blocks, pendants, 

etc.) is either lowered to the ground or blocked securely 

before servicing, adjusting, or repairing winch.

2.  Be sure personnel are clear of work area BEFORE op-

erating winch.

3.  Read all warning and caution tags provided for safe 

operation and service of the winch and become familiar 

with the operation and function of all controls before 

operating the winch.

4.  Inspect rigging and winch at the beginning of each work 

shift. Defects should be corrected immediately. Do not 

operate a winch with defects.

5.  Keep equipment in good operating condition. Perform 

scheduled servicing and adjustments listed in the Pre-

ventive Maintenance section of this manual.

6.  An equipment warm-up procedure is recommended for 

all start-ups and essential at ambient temperatures be-

low +40°F (+4°C). Refer to Warm-up Procedure listed in 

the Preventive Maintenance section of this manual.

7. 

Do not exceed the maximum pressure (PSI, bar) or flow 

(GPM, lpm) stated in the winch specifications found in 

the specific sales brochure.

8.  Operate winch line speeds to match job conditions.

9.  Protective gloves should be worn when handling wire/

synthetic rope.

10. Never attempt to handle wire/synthetic rope when the 

hook end is not free. Keep all parts of body and cloth-

ing clear of cable rollers, cable entry area of fairleads, 

sheaves, and winch drum.

11.  When winding wire/synthetic rope on the winch drum, 

never attempt to maintain tension by allowing wire rope 

to slip through hands. Always use hand-over-hand tech-

nique.

12. Never use wire/synthetic rope with broken strands. Re-

place wire/synthetic rope that is damaged. Refer to wire 

rope supplier manual.

13. Do not weld on any part of the winch without approval 

from PACCAR Winch Engineering.

14. Use recommended hydraulic oil and gear lubricant.

15. Keep hydraulic system clean and free from contamina-

tion at all times.

16. Use correct cable anchor for wire/synthetic rope and 

pocket in drum.

17. Do not use knots to secure or attach wire/synthetic rope.

18. The BRADEN-designed wire/synthetic rope anchors are 

not intended to support the rated load. ALWAYS main-

tain a minimum of five wraps of wire rope on the drum or 

a minimum of eight wraps of synthetic rope on the drum. 

It is recommended that the last five wraps of wire rope or 

last eight wraps of synthetic rope be painted bright red to 

serve as a visual reminder.

19. Never attempt to clean, oil or perform any maintenance 

on a machine with the engine or prime mover running, 

unless instructed to do so in this manual.

20. Never operate winch controls unless you are properly 

positioned at the operators station and you are sure per-

sonnel are clear of the work area.

21. Assure that personnel who are responsible for hand sig-

nals are clearly visible and that the signals to be used 

are thoroughly understood by everyone.

22. Ground personnel should stay in view of the operator 

and clear of the winch drum. Do not allow ground per-

sonnel near wire/synthetic rope under tension. A safe 

distance of 1-1/2 times the working length of the rope 

should be maintained.

23. Install guarding to prevent personnel from getting any 

part of body or clothing caught at a point where the cable 

is wrapped onto the drum or drawn through guide rollers 

or potential pinch points.

24. 

Install switches or valves that will shut off power to the 

winch, in locations where they can be reached by any-

one entangled in the rope before being drawn into the 

winch or any pinch point.

Safety for operators and ground personnel is of prime concern. Always take the necessary precautions to ensure safety 

to others as well as yourself. To ensure safety, the prime mover and winch must be operated with care and concern by 

the operator for the equipment, and a thorough knowledge of the machine’s performance capabilities. The following 

recommendations are offered as a general safety guide. Local rules and regulations will also apply.
