Testing
Operational Test
Prior to initial use, all new or repaired winches shall be tested to
ensure proper operation.
1. Check oil level in motor, reduction gear assembly and disc
brake are correct. Top off levels as required before operation
as described in the “LUBRICATION” section.
2. To initially ‘break in’ new or overhauled motors operate
without load, in both directions, for 15 minutes at 100 - 200
RPM.
3. New Drum Brake Band Lining Run-in Procedure: All new
drum brake band linings require a ‘run-in’ period. Operate
the winch without load in the payout direction while
gradually applying the brake. Allow the brake to slip for
approximately one minute. Winch motor may stall as drum
brake band lining fully engages. Do not allow brake to
overheat.
4. Check operation of brakes. Adjust if necessary as described
in the “MAINTENANCE” section.
5. Check operation of limit switches, locking mechanisms and
all safety devices when equipped.
6. Check foundation mounting fasteners are secure.
7. Install drum guard when provided.
Load Test
Prior to initial use, all new or extensively repaired winches shall
be load tested by or under the direction of a person trained in
safety and operation of this winch and a written report furnished
confirming the rating of winch. Test loads shall not be less than
100% of rated line pull and should not exceed 125% of rated line
pull. To test winch at 125% of rated load apply following load
with wire rope on the first layer of the drum:
FA5 Winch 19,970 lb. (9,058 kg)
FA5T Winch 19,970 lb. (9,058 kg)
NOTICE
• Testing to more than 125% of rated line pull may be required
to comply with standards and regulations set forth in areas
outside of the USA.
Limit Switches
Operate winch through three complete cycles to ensure consistent
limit switch operation within +/- 2 feet (0.6 metre) of set points.
Refer to ‘Limit Switch Adjustment’
on page 27 in
“MAINTENANCE” section to establish set points.
