Tie Down 66 Actuator - Manual (Page 3)

6. While towing, if the actuator appears to be knocking against the hitch ball while starting or stopping, check brake fluid reservoir
and fill if below 3/8” full from the top. Dampening shock absorber requires sufficient brake fluid in order to retard movement
against hitch ball during towing.
WARNING - DISC BRAKE USE
When installing disc brakes to use with part #47200/86167 actuator, a check valve inside the actuator must be disabled. See disc
brake installation instructions. If you do not properly disable the check valve, pressure will remain in the system causing the disc
brakes to drag, overheat and fail. Part #47201/86165 actuator, has a disabled check valve for use on disc brakes - DO NOT use
part #47201/86165 on drum brakes.
WARNING
Actuator and brakes should always be flushed with fresh water after using trailer in corrosive conditions. This includes salt water,
fertilizers and other corrosive materials. Before storing trailer remove brakes and clean thoroughly. It is also wise to repack the
bearings at the same time. Failure to properly and adequately maintain the actuator could cause serious damage, injury or death.
WARNING
The breakaway system is not designed to operate if the trailer does not separate completely from the tow vehicle, or if the tongue
goes under the rear of the tow vehicle.
WARNING
In the event that the breakaway system is used, check all system components (cable, S-hooks, etc.) for proper working order.
Replace any damaged parts with genuine Tie Down parts only.
WARNING
When re-setting the break a way system keep hands and fingers clear as you re-set the mechanism, hydraulic pressure held in the
system may cause the assembly to snap back suddenly.
WARNING
AVOID sharp turns, which can cause the actuator to bind or jackknife against the tow vehicle or cause a bend in the tongue. Either
can damage the actuator causing brake failure. AVOID towing trailer across large bumps or dips that may over stress the connec-
tion between the trailer and tow vehicle, as this could result in damage to the actuator.
WARNING
DO NOT REUSE BRAKE FLUID. Always use fresh DOT 3 fluid from a fresh container. Failure to maintain proper levels of fluid in the
reservoir will cause brake failure.
WARNING
Failure to install the hitch pin before towing can result in accidental opening of the coupler hitch latch which can lead to the trailer
coming off of the hitch ball causing serious damage, injury or death. If pin will not fit into the front lower hole, the coupler is not
attached properly. Re-set coupler on hitch ball.
WARNING
A minimum of 5% tongue weight and a maximum 10% tongue weight of the trailer GVWR must be located on the hitch ball. The
Trailer tongue should be parallel to the ground. Too much weight can cause premature brake actuation and loss of control of the
towing vehicle. To little tongue weight can cause the trailer to fishtail, resulting in loss of control of the tow vehicle and trailer
(total trailer weight GVWR includes weight of the trailer plus load).
WARNING
A loose fit between the coupler and hitch ball can cause the actuator and hitch ball to separate, causing serious damage, injury or
death. Check coupler every time prior to towing and at each stop on long trips. Always make certain that coupler latch safety pin is
securely installed into coupler latch.
WARNING
When using drum or disc brakes on tandem axle trailers, both axles must be installed with brakes, Failure to install brakes on
both axles will result in loss of braking performance, overheating of brakes & wheel hub, and significantly reduce brake pad life.
WARNING
NEVER ALLOW THE COUPLER LATCH SAFETY PIN TO REMAIN IN THE REVERSE LOCKOUT POSITION HOLE.
AFTER REVERSE MANEUVERING, ALWAYS INSERT COUPLER LATCH SAFETY PIN BACK INTO COUPLER
LATCH. FAILURE TO REMOVE SAFETY PIN FROM REVERSE LOCK OUT POSITION HOLE WILL PREVENT
FORWARD MOVEMENT BREAKING WHICH CAN RESULT IN SERIOUS PROPERTY DAMAGE, INJURY OR DEATH.
