SAFETY
DO NOT INSTALL, OPERATE OR USE THIS EQUIPMENT UNTIL THE FOLLOWING
OPERATING AND SAFETY INSTRUCTIONS HAVE BEEN READ AND UNDERSTOOD.
This symbol is used to bring attention to safety precautions and instructions. When
you see this symbol, be alert and pay attention to all instructions. YOUR PERSONAL
SAFETY IS INVOLVED.
1. Blue Ox tow bars should only be used with vehicles
that are towable or have been equipped to be towed.
2. Follow towing procedures in the vehicle Owner's
Manual.
3. Tow with steering wheel in the unlocked position.
4. Be sure the front end of the towed vehicle is properly
aligned. Misaligned vehicles may cause poor
tracking or abnormal wear on the tires.
5. The use of safety cables or chains is required by
law in most states of the United States, as well as
Canadian territories and provinces. Follow state
or territory recommendations.
6. Check clearance between vehicles in all turning
situations. Check the height difference in your
towing set up and make appropriate adjustments
by following the recommendations of the tow bar
instruction manual.
7. Rear lighting is required on the towed vehicle. Blue
Ox offers lighting kits to cover all of your lighting
needs. Contact your Blue Ox representative for more
information.
8. Prior to usage, inspect all towing equipment for
cracked welds, missing or worn parts, and loose
bolts.
9. Disconnect the towed vehicle from the towing vehicle
before backing up. Do Not Back Up While Vehicles
Are Connected! Damage to both vehicles and the
towing system may occur. The towed vehicle may
jack knife, causing abnormal stress to the tow bar,
car chassis, baseplate and/or pintle hitch of the
towing vehicle. These abnormal stresses may cause
damage that may go undetected.
10. Avoid sharp turns and rough terrain. Check towing
set up after any emergency situation and/or
periodically on a long trip.
11. Do not use the towed vehicle for storing luggage,
equipment, etc. This may cause you to exceed
the towing capacity of the tow bar, baseplate, and
its accessories.
3. Place the pintle ring on pintle hitch of the
towing vehicle, close the pintle hitch locking
lever and secure the clip or lock.
4. Partially extend one leg. The legs are held
in with a "soft" latch. Pulling out on the leg
will disengage this latch. Place the triple lug
between the attachment tabs on the baseplate,
and secure with the 1/2" pin and quick pin.
Place the 1/2" pin and quick pin so the quick
pin is away from any object that could open it
and allow it to disengage. Install remaining leg
in a similar manner.
CAUTION: As with any mechanical
product, care should be taken during installation,
operation, and storage to prevent your fingers from
being pinched, cut or otherwise injured.
1. Stop the towing vehicle on a straight, at,
and level surface and engage the parking
brake. Drive the towed vehicle behind the
towing vehicle in the approximate towing
position and engage the parking brake of the
towed vehicle.
2. Install safety chains, lighting system and
auxiliary braking system.
INITIAL INSTALLATION
If the tow bar is in an accident, it must be replaced. DO NOT use it again!
An accident can cause unseen damage and using it again could result in
more damage or serious injury. DO NOT use the tow bar if it is damaged or
missing parts.

EXTENDING
EXTENDING TOW BAR
CAUTION: It is possible to extend the tow bar by
driving away with the towing vehicle. THIS IS NOT
RECOMMENDED. Side to side movement of the towed
vehicle may occur if the legs do not lock into position.
Towing any vehicle until the operator has confirmed
that the leg latches have been properly locked IS
NOT RECOMMENDED.
1. After connecting both legs, start the towed vehicle,
disengage parking brake, pull backward slowly with
the towed vehicle until one or both of the locking
handles are engaged and locked. NOTE: If only
one locking handle is locked, turn the towed
vehicle's steering wheel (with the engine running
to make turning easier) toward the unlocked tow
bar leg approximately 1/2 to 3/4 turn. Set up the
transmission for towing, (See SAFETY Section
- Page 2) stop the engine and leave the steering
wheel in the unlocked position. The steering wheel
on the towed vehicle must be unlocked at all times
while towing. Failure to do so will create hazardous
driving conditions. Pull the towing vehicle forward
one to two feet until the unlatched leg locks into
place. IMPORTANT: Check to insure both legs are
latched properly before towing.
UNHOOKING / STORING
1. Stop the towing vehicle with vehicle in tow in a
straight line on a at and level surface and set the
parking brake. (Doing this minimizes the pressure
exerted on the tow bar latches, and will aid in
releasing the locking handles.)
2. Place the towed vehicle in park (for automatic
transmissions) or securely in first gear (for manual
transmissions).
3. Unhook and store the electrical cables, safety chains
and any auxiliary braking system.
4. DO NOT hammer or force the locking handles to
release. If difficulty is encountered in releasing the
locking handles, try the following: Turn the towed
vehicle's steering wheel (with the engine running to
make turning easier) all the way to the right, all the
way to the left, then bring back to center. This should
relieve any pressure being placed on the tow bar
handles from the towed vehicle.
5. Remove quick pins and 1/2" pins from the driver's
side and passenger's side of the baseplate, laying
the legs on the ground.
6. Remove the clip or lock from the pintle hitch locking
lever and lift up. Lift the ring off the hitch, cover and
store in a clean, dry place.
TIPS
1. Keep the tow bar covered when not in use, on or off
of the towing vehicle. This will cut down on the dust
and dirt build-up on the inside legs and latches of the
tow bar.
2. Periodically, clean the entire surface of the tow bar
with a mild soap and water solution. Wipe dry with
a clean cloth. Use only dry silicone spray to prevent
dirt and outside elements build-up on tow bar legs.
3. Prior to each usage, inspect all towing equipment
for cracked welds, missing or worn parts, and loose
bolts. If any of the above conditions are present,
replace all missing, worn or loose parts. Contact
Blue Ox if broken or cracked welds are present and
DO NOT USE!!
4. Do not back up when towing. The towed vehicle may
jack knife causing abnormal stress to the tow bar, car
chassis, baseplate and hitch receiver of the towing
vehicle.
5. In normal straight line towing conditions, both
legs will be in tension. Due to the design of the
latch, both handles will feel loose. During turning,
braking or parking, one or both of the legs may
be in compression. This will make the handles
feel stiff or tight. In different towing set ups and/
or situations, the two locking mechanisms could
be in compression or tension or any combination
of both. Having one lock in tension and one in
compression may cause the operator to think that
one leg is locked and one is not. When the legs are
fully extended and the springs are holding the latch
handles up, the legs are locked and ready to tow
whether in tension or compression.
6. Blue Ox tow bars are designed for the pintle ring
to be parallel to the ground when towing. If
the pintle tow bar is at an angle, damage or
accident can occur.

brake.
2. Place the towed vehicle in park (for automatic transmissions) or first gear (for manual transmissions).

QUICK REFERENCE GUIDE
IMPORTANT: Use only genuine factory replacement parts on your tow bar. Do not substitute homemade or
nontypical parts. If a bolt is lost or in need of replacement, for your safety and the preservation of your tow bar,
be sure to use a replacement bolt of the same grade (usually Grade 5). Failing to follow and/or altering these
installation instructions, in either installation or required equipment, will void the manufacturer's warranty. Towing
behind a non-motorized vehicle will void the warranty.
Repair parts may be ordered through your nearest Blue Ox dealer or distributor.

WARNING: Ensure that your towing vehicle is of adequate size to
properly control your towed vehicle. The weight and braking capacity
should be large enough to handle both vehicles in an emergency situation.
Check your towing vehicle manufacturers recommendations for towing,
hitch load, and braking capacities. The hitch, ball, motorhome chassis, and
safety cables (each individual cable) need to be rated at a minimum for the
weight of the vehicle being towed.
