4. Check with your state motor vehicle department for laws concerning minimum
trailer brake requirements. Some states may require brakes on all axles.
5. Road test trailer a short distance to activate the actuator several times. Check fluid
level again. Remember, low brake fluid levels will result in hitch ball knocking.
6. When testing is completed, make sure master cylinder is filled to 3/8” below the top
of the reservoir and filler cap is securely in place. Road test again to make sure
brakes work properly.
RATED CAPACITY: Maximum Actuator Capacity: 7500 lbs.
Gross Load, 750 lbs. Maximum Tongue Load
The actual in-service rating is limited to that of the ball and hitch being used or the
trailer manufacturer’s G.V.W.R. shown on the certification label, whichever is lower
(Note: G.V.W.R. is the Gross Vehicle Weight Rating which includes the trailer and the load
weight as a Total Gross Weight).
Hitching The Trailer
1. The vehicle, towing hitch and ball must have a rating equal to or greater than
trailer G.V.W.R..
2. Model 750E will accept 2” or 50mm trailer hitch balls only. Trailer balls larger than
2.00” (50mm) or out of round will not fit the coupler or may result in coupler
failure. Balls smaller than 1.95” can cause shock loading and sudden
disconnection. Make certain ball latch is in correct position to retain the hitch ball.
Push latch until safety latch engages plate below latch. Insert safety pin into forward
hole as a safety lock for the hitch ball coupler prior to towing. Do not tow trailer if
coupler is damaged.
3. Connect safety cables or chains using crossed pattern under tongue, or follow
trailer manufacturer’s directions.
4. Connect actuator breakaway cable S-hook to the tow vehicle only. Do not
connect S-hook to the safety cables or chains.
5. The breakaway system is designed to only operate after the trailer detaches from
the tow vehicle and the safety chains have failed. The breakaway is not a parking
brake. Do not use as such.
6. If the breakaway is accidentally applied, insert a flat bladed screwdriver into the
spring clip on the side of the actuator and pry sideways pressure to release,
see page 8.
7. Any control devices that restrict operation of the actuator cannot be used. This
includes certain sway control devices. The actuator must be free to telescope in
response to braking requirements.
8.
Equalizing or weight distributing hitches may be used, that are designed to use with
surge brake actuators, allow six to eight inches free chain length.
