MAYCO LS600 PUMP — OPERATION AND PARTS MANUAL — REV. #4 (9/15/11) — PAGE 53
If the coupler cannot be secured to the hitch ball, do
not tow the trailer.
Call your dealer for assistance. Lower
the trailer so that its entire tongue weight is held by the
hitch and continue retracting the jack to its fully retracted
position.
Overloading can damage the tongue jack.
DO NOT
use the tongue jack to raise the
tow vehicle more than 1 inch.
Rock the ball to make sure it is tightened to the hitch,
and visually check that the hitch ball nut is solid against
the lock washer and hitch frame.
Wipe the inside and outside of the coupler. Clean and
visually inspect it for cracks and deformations. Feel
the inside of the coupler for worn spots and pits.
Be sure the coupler is secured tightly to the tongue of
the trailer. All coupler fasteners must be visibly solid
against the trailer frame.
The bottom surface of the coupler must be above the
top of the hitch ball. Use the tongue jackstand to
support the trailer tongue. Wood or concrete blocks
may also be used.
Figure 53. Ball Hitch Coupling Mechanism
Lower the trailer (Figure 53) until the coupler fully
engages the hitch ball.
Engage the coupler locking mechanism. In the engaged
position, the locking mechanism securely holds the
coupler to the hitch ball.
Insert a pin or lock through the hole in the locking
mechanism.
Be sure the coupler is all the way on the hitch ball and
the locking mechanism is engaged. A properly engaged
locking mechanism will allow the coupler to raise the
rear of the tow vehicle. Using the trailer jackstand,
verify that you can raise the rear of the tow vehicle by
1-inch after the coupler is locked to the hitch.
Lower the trailer so that its entire tongue weight is held
by the hitch.
Raise the jackstand to a height where it will not interfere
with the road.
A loose hitchball nut can result in uncoupling, leading to death or
serious injury.
Be sure the hitch ball is tight to the hitch before coupling the trailer.
WARNING
-
Uncoupled Hitch Ball
Coupling the Trailer to the Tow Vehicle (Ball Coupler)
Lubricate the hitch ball and the inside of the coupler
with a thin layer of automotive bearing grease.
Slowly back up the tow vehicle so that the hitch ball is
near or aligned under the coupler.
Using the jackstand at the front of trailer (tongue), turn
the jackstand crank handle to raise the trailer. If the
ball coupler does not line up with the hitch ball, adjust
the position of the tow vehicle.
Open the coupler locking mechanism. Ball couplers
have a locking mechanism with an internal moving
piece and an outside handle. In the open position, the
coupler is able to drop fully onto the hitch ball.
A worn, cracked or corroded hitch ball can fail while towing, and may
result in death or serious injury.
Before coupling trailer, inspect the hitch ball for wear, corrosion and
cracks.
Replace worn or damaged hitch ball.
