Personal and Work Area Safety (continued)

Wheel Chocks keep work area clean and
well lighted. Keep spectators and chil-
dren out of the work area.
3. Use of the Tandem Wheel Chocks
A. Do not modify this product and do not
use this product for purposes that it was
not designed for. Never attempt to use the
Wheel Chocks as a jack or brace to lift or
hold any object.
B. This product is designed to t be-
tween 2 adjacent wheels on each side of
a trailer/vehicle. Once locked in place,
the Wheel Chock will minimize wheel
movement and rocking motion while the
trailer/vehicle is parked. Always use both
Wheel Chocks (one on each side of the
trailer/vehicle) at the same time. Never use
only one Wheel Chock.
C. The Tandem Wheel Chocks are adjust-
able and can be used if there is a 1/2” to 6”
distance between each tire.
D. Be aware of the
nger/hand pinching risk while adjusting
the Wheel Chocks for use. Use caution
when pulling open, or closing the Wheel
Chock while it is being tted for the opening
between the two tires. Do not wear loose
clothing, jewelry or dangling objects. Keep
hair, clothing and work gloves clear of mov-
ing parts.
E. Detailed set up work is required to adjust
the Wheel Chocks before use. If you are not
experienced or capable of doing this type of
work safely, the Wheel Chocks should be set
up by a qualied service technician.
F. This product is not a toy and should be lo-
cated in an area away from children and out
of reach of children. Do not allow children
to play with this product. When not in use,
Wheel Chocks should be stored in a safe
location, out of reach of children.
G. Before each use, check the overall con-
dition of each Wheel Chock. Make sure that
each Wheel Chock adjusts properly. Check
that no structural damage is present. Make
sure that all rivets and hardware are in good
condition. Never use a damaged Wheel
Chock. A damaged Wheel Chock should be
replaced (and not repaired). Make sure that
tires on the trailer/vehicle are properly inat-
ed to manufacturer’s recommendation.
H. Only use the Wheel Chocks if the trailer/
vehicle is located on a at, level solid sur-
face. A trailer/vehicle on a non-level surface
can become an out-of-control load.
I. Never asssume that this Tandem Wheel
Chock is the main brake for the trailer/
vehicle. Always use independent braking
(emergency brake for a vehicle), and wheel
blocks, or wheel wedges, for a trailer, to
safely keep the trailer/vehicle in a parked
position.
J. It is the responsibility of the owner of this
product to make sure that everyone using
the Wheel Chocks reads and understands
the warnings and instructions contained in
this instruction manual.
K. MAXXHAUL is not responsible for any
damage to the Tandem Wheel Chocks or
trailer/vehicle, or wheels/tires of the trailer/
vehicle occuring while the Tandem Wheel
Chocks are in place.
L. Save packaging information, warnings
and this manual. They contain important in-
formation and must always remain readable.
Contact MAXXHAUL for replacements.

wheels, with the handle
in the “Down” locked
position, the Wheel
Chock minimizes wheel
movement and rocking
motion while trailer/
vehicle is parked.
C. Wheel Chock Set-Up:
Initially it will take a bit of time to properly
wheels of your trailer/vehicle. If used again
on the same trailer/vehicle, Chocks will not
have to be re-adjusted before each use.
Note that out of the box, each Wheel Chock
is folded inward in it’s most narrow position.
hand pinching risk while adjusting the
Wheel Chocks for use.
With the Handle in the “UP” vertical position,
carefully open up (make wider) the Wheel
Chock. This will expose more threads on
the shaft.
The adjustment Nut will eventually be
threaded up the shaft once the proper
“width” of the Wheel Chock is determined.
Move the Wheel Chock into place between
the two tires. Note the desired width of the
Wheel Chock (light contact with each tire).
Remove the Wheel Chock and with handle
still in the “UP” vertical position, begin mov-
ing the adjustment Nut up the shaft (using
1/2” combination wrench - not included) -
