• Verify the safety cables are properly at-
tached to the tow vehicle.
• Verify the emergency brake cable is at-
tached properly to the tow vehicle.
• Verify the boat is properly loaded on
the trailer and properly tied down to the
trailer.
• Verify and/or correct tire pressure on
both the tow vehicle and trailer.
• Ensure the lug nuts are properly torqued.
(This must also be done after the rst
25 miles of towing and every 100 miles
thereafter, at a minimum. MasterCraft
recommends checking this more often.
At each fuel or rest stop is not exces-
sive.)
• Verify the wheel jack is retracted, up and
in the locked position prior to towing.
• Verify the tow vehicle has not exceeded
the load capacity prior to towing.
• Check the guide pole bars to ensure they
are tight.
• Check that all items are securely fas-
tened on and in the trailer.
Every three to six months or 250 miles,
whichever occurs rst (in addition to
above):
• Grease the trailer jack.
• Oil the trailer jack handle in accordance
with the manufacturer’s recommenda-
tions.
• Examine the entire trailer for any abnor-
malities or damage.
• Examine the trailer bunks for any signs
of abnormal wear.
• Lubricate all the rollers on the trailer
with a light coat of oil.

• To assure the bearings are in good work-
ing order, check the bearing adjustment
at least once a year by following this
procedure: Jack up one side of the trailer.
(Becertaintousejackstandsandcheck
the trailer wheels to keep the trailer
from moving during the inspection.)
Grip the edge of the tire and see if it can
be rocked or moved. If the outer edge of
the tire moves more than 1/8” at all, the
bearings may need to be readjusted.
• Inspect the tow hitch for corrosion or
damage. Repair or replace components
as necessary.
• Check for wear on the hitch ball. If the
ball is worn, it is UNSAFE and must be
replaced.
• Check the coupler mechanism for
smooth operation. If the button is hard to
push or the latch handle does not spring
open after being disengaged, lubricate
the points on the coupler latch mecha-
nism.
• Check the actuator for excessive wear.
If the outer member is rubbing against
the inner, wear marks will show on top
of the coupler just forward of the outer
member. Contact an authorized Master-
Craft dealer for replacement parts.
• Check the actuator travel. Excessive ac-
tuator travel (over one inch) when the
brakes are applied indicates air in the
brake lines.
• Check the brake uid in the master cyl-
inder reservoir. On the UFP actuator, to
gain access to the reservoir, remove the
cap on top of the actuator. Clean the area
around the master cylinder plug. Use
a screwdriver to carefully pry off the
plug. Make sure the rubber seal around
the opening is in good condition. Clean
brake uid off the level indicator on the
plug. Re-install and remove the plug.
Brake uid should just touch the end of
the level indicator. On the Tie Down En-
gineering actuator, remove the cap to the
