Care and Use of BOA Winches
MAINTENANCE:
•
The gear mechanism requires periodic lubrication to maintain proper function. It is important to
use premium grade 2 lithium based bearing grease with molydisulfide.
•
The grease fitting is located on the back of the gear housing and mates with a standard zerk
adapter on a grease gun.
•
Inject grease until it comes out either the main shaft bushing or the input hex drive shaft
bushing.
OPERATION:
•
Turn the input hex drive counterclockwise to disengage from the main gear. The hex drive shaft
will move outward from the gear housing.
•
With the gears disengaged, the main shaft can be turned by hand using the hand crank.
•
Before tensioning, pull excess webbing through mandrel slot. When the tie down is fully
tensioned, two (2) to four (4) wraps of webbing shall be on the mandrel (4 to 8 layers of
webbing). Additional wraps can cause damage to the winch due to excessive torque, or make it
difficult to apply or release tension.
•
Turn the hex drive clockwise to engage the gears and continue to turn clockwise to apply
tension to the binder. Applying 40 to 60 lb to the end of the torque crank will result in
approximately 1500 lb of strap tension. By increasing the applied force to the torque crank to
100 to 140 lb, strap tension of approximately 2200 lb can be achieved. Additional strap tension
is not needed to adequately secure typical cargo.
•
When tensioning or releasing the winch in rain, snow, or other slippery conditions, carefully
position your feet and body to prevent a fall.
•
Winches should never be loaded in excess of their working load limit (WLL).
•
Winches should be used in accordance with all applicable federal, state, local, and industry
regulations applicable to cargo securement.
•
A training program for operators is recommended for the correct and safe use of cargo
securement systems.
