3. Do not allow untrained persons to operate the crane.
4. Use the crane for lifting only. Do not work under a load that is supported
only by the crane.
5. Stabilize the load. Ensure that the load remains stable at all times. Lift
deadweight only.
6. Know the weight of the load being lifted. DO NOT overload the crane
beyond the rated capacity of each specied boom position. Overloading
can cause damage or failure of the crane.
7. The vehicle with the crane should be on a level surface capable of
sustaining the weight of the vehicle and load. Use of the crane on other
than level surfaces can result in crane instability and possible loss of load
or tipping of the vehicle.
8. Make sure there is enough clearance around the crane and the load for
movement.
9. Never attempt to use the crane unless it is properly lled with hydraulic
uid. Do not use brake uid or any other improper uid and avoid mixing
dierent types of oil when adding hydraulic oil.
10. Inspect the tool before each use. DO NOT use if bent, broken, cracked,
leaking, otherwise damaged, if any suspect parts are noticed or it has
been subjected to a shock load.
11. Check to ensure that all applicable bolts and nuts are rmly tightened.
12. Store the crane with the boom fully lowered, winch cable retracted,
hydraulic ram valve closed and position the boom over the vehicle's wheel
well when storing or driving.
JACK PRECAUTIONS
1. Do not use a handle extension for the jack handle.
2. Make sure the load is stable, so it does not shift when lifting or lowering.
3. Ensure that there are no obstructions under the load and that the area is
clear before lowering the device.
4. Lower the load in a slow and controlled manner to prevent shock loading.
Shock loading may cause to fail and lead to property damage and/or

4. Use only with accessories rated to handle the forces exerted by the device
during operation. Other accessories may break and forcefully launch
pieces.
5. Do not place your hands between moving components.
WINCH SAFETY
1. All users must understand the operation of all controls and learn how to
stop the winch quickly in case of emergency.
2. Keep hands clear of the winch and wire rope when spooling the line in or
out. Hold the wire rope by the strap. Fingers caught in the hook may be
pulled into the mechanism and crushed or pinched.
3. Never fully extend the wire rope while under load. Keep four complete
turns of the wire rope around the winch drum.
4. Do not exceed the winch load capacity.
5. Do not use the winch if damaged or it was subjected to a dynamic
shock load. Have the winch inspected and repaired by a qualied service
technician.
6. Always use proper couplings when connecting the winch cable hook,
sling, eyebolt or other accessory to the load. Never connect the hook back
to the wire rope. This causes wire rope damage. Always use a sling or
chain of suitable strength.
7. Do not use inappropriate attachments to extend the length of the winch
wire rope.
8. After moving an item with the winch, secure the item. Do not rely on the
winch to hold it for an extended period.
9. Make sure the rope spools onto the drum in touching wraps. A rope that
cannot move without impediment can create a dangerous situation that
can injury you or a bystander or damage the load and/or the winch.
10. Never lift people or hoist loads over people.
11. Never come in-between the winch and the load when operating

HYDRAULIC PRECAUTIONS
DANGER! Seek immediate medical attention if hydraulic uid under
pressure penetrates your skin. See Injection Injury precautions for
instructions before using a pressurized hydraulic system.
1. Do not touch or handle components while under pressure. Hydraulic uid
escaping under pressure has sucient force to penetrate your clothing
and skin. A pinpoint hole may inject hydraulic uid into your body. Seek
immediate medical attention if this occurs (see Injection Injury).
2. Never exceed the hydraulic system’s load capacity (see Specications).
3. Do not adjust the hydraulic system’s relief setting. The settings are preset
by the factory.
4. Hydraulic oil under pressure is hot and can cause a burn injury if touched,
sprayed or spilled. Allow the hydraulic system to cool before conducting
maintenance.
5. Hydraulic components require regular inspection. Release all pressure
from the system before you inspect it. Replace damaged hydraulic parts
with identical manufacturer's components.
6. Do not attempt makeshift repairs to a hydraulic system. Such repairs can
fail suddenly and create a hazardous condition.
7. Hydraulic uid has a combustible ash point of 200°F (93°F). Do not
expose the uid to an ignition source.
8. Change your clothing immediately if sprayed with hydraulic uid. Store
clothing or rags contaminated with hydraulic uid in an approved metal
safety can with a spring-closing lid and venting designed to contain a re.
9. Only use hydraulic uid in the pump. Do not substitute or mix brake uid,
or any other uid, with the hydraulic uid. This can result in a pump
failure and injure the user or bystander. It may also damage the pump.
INJECTION INJURY
DANGER! Seek immediate, professional medical treatment if uid
penetrates your skin. It may feel like a pricking or sting. Do not wait
for the appearance of symptoms. A toxic reaction can occur from the
exposure. Delay in treatment can lead to amputation or death.
Inform the medical sta that you have a uid penetration injury as soon as you
arrive at the medical facility. The severity of the symptoms will depend on the
type of uid injected. Bring the Safety Data Sheet for the uid with you to the
medical facility if possible.
V1.0 TRUCK MOUNT CRANE 8732315
Page 7 www.princessauto.com / 1-800-665-8685

INJECTION PRECAUTIONS
Fluid can penetrate the skin at 100 PSI pressure. Fluid escaping under pressure
from the tool has sucient force to penetrate your clothing and skin. Follow
the precautions below to avoid an injection injury.
1. Always check for leaks wearing a face shield, safety goggles, rubberized
gloves and protective clothes.
2. Release all pressure from the system before you inspect it.
3. Do not use your hands to detect a leak. Use a large piece of wood,
cardboard or paper and watch for discolouration.
4. Replace damaged parts with identical manufacturer's components to
ensure it is rated to handle the pressure.
UNPACKING
WARNING! Do not operate the tool if any part is missing. Replace
the missing part before operating. Failure to do so could result in a

ASSEMBLY & INSTALLATION
ASSEMBLING THE CRANE
Some components are heavy and dicult to maneuver while installing.
Have another person available to help you during installation.
1. Place the base in the truck bed and check for proper clearance when the
crane is in use and when stored. A right rear corner mount is typical.
a. A wood truck oor will require the installation of a 3/8 in. thick steel
plate approximately six to eight inches larger than the base plate on
top of the wooden deck. If the oor is heavy metal and ribbed, no
metal plate is required under the crane base plate, but lling in the
ribbed oor to level it may be required. The base may now be placed
in position and used to locate the mounting holes through the truck
bed and back plate.
b. Dierent truck models may require additional bracing as the load
will be directed over the largest area possible. If additional bracing
is desired, install a brace which crosses both sides of the truck and
may be used with an outrigger, stabilizer or jack leg holder to keep
the truck stable during lifting operations.
FIGURE 1.

2. Check the mounting location below the truck bed
to avoid wiring, gas tanks, muers, etc. Adjust the
base position if needed to avoid puncturing the
understructure when drilling.
3. Use the base as a template and mark the holes that
you will use to mount the base to the truck bed.
Move the base aside.
4. Drill holes into the truck bed. Make sure the drill and
drill bit are suitable for drilling through the metal.
Use cutting oil if necessary.
5. Reposition the base over the holes. Secure in place
with bolts, washers and nuts (sold separately). Only
use hardware that exceeds the weight capacity of
the crane.
6. Insert the bearing (#43) into the base. Screw the base
handle (#34) into the base until the bearing is held in
place (Fig. 2).
7. Slide the post over the base and align the holes in
each (Fig. 3). Insert a bolt (#27) through each hole.
Slide a washer (#8) and lock washer (#7) over the
bolts and secure with a nut (#6).
8. Insert the boom into the post’s top bracket (Fig. 4).
Position the large pulley inside the boom so the
bushings align with the bolt holes. Insert a bolt (#42)
through the bolt holes. Secure with a washer (#24),
lock washer (#23) and nut (#22).
• Ensure the connection point for the hydraulic
jack is on the bottom and near the post when
connecting the boom.
9. Follow the instructions for

wire compacted. Run the winch with a light load several times, before normal
use.
Also use a weight when spooling the wire rope onto the winch. This will
provide the correct tension when spooling.
INSTALLING A WIRE ROPE
1. Remove the bolt that connects the boom and boom
extension and set aside.
2. Push the boom extension into the boom.
3. Lift the boom so it is at a slight upward angle. The
angle will hold the boom extension in place.
4. Insert the end of the wire rope through the hole in the
bottom of the boom extension. Pull several feet of wire
rope through the hole.
5. Feed the wire rope down the boom extension and
boom until it comes out the other end.
6. Place the wire rope onto the pulley in the boom and
boom extension.
7. Continue pulling wire rope out of the boom until you
are sure it won't be pulled back by its own weight.
8. Mount and wrap the wire rope onto the winch.
MOUNTING A NEW WIRE ROPE
1. Pull the end of the wire rope over the top of
the drum.
2. Insert the wire rope end through a side hole
in the drum from the inside. Pull about one to
two feet of wire rope out.
3. Guide the wire rope into the next hole and pull
the excess through. Leave enough line to form
a large loop.
4. Guide the wire rope through the next hole from the inside and pull the
excess through.
5. Insert the end of the wire ripe under the large loop. The end must extend
past the loop, but stay within the edge of the drum to avoid impeding
rotation.

wire rope's slack by pulling it back through the holes, until the loop traps
the rope end.
7. Reel the new wire rope onto the drum by turning the handle, being careful
not to allow kinking.
8. Test the winch for proper operation.
MOUNTING A NEW WIRE ROPE
1. Route the end of the new wire rope under the bushing and through the
hole to the outside of the drum.
2. Insert the wire rope under the cable clamp.
3. Tighten the cable nut securely.
4. Reel the new wire rope onto the drum by turning the handle, being careful
not to allow kinking.
5. Test the winch for proper operation.
INSTALLING THE CHAIN AND HOOK
Make sure the chain, hook and hardware are rated to exceed the crane's weight
capacity.
1. Choose a short length of chain to avoid problems with clearing obstacles
when raising the load.
2. Attach a suitable shackle to the top chain link.
3. Align the shackle openings with the connection point on the boom
extension. Insert a bolt through the shackle and the connection point.
Secure the bolt with a nut or tighten if the shackle is threaded.
4. Attach another shackle and a hook to the bottom chain link, if the chain
does not have one already.
OPERATIONS
WARNING! No one other than the people involved in moving the load
should be in or on the vehicle. Anyone near the vehicle may be seriously
injured or killed if the load falls or the vehicle tips over under a heavy
load. Ensure each person has an unobstructed escape route away from
the work area.
V1.0 TRUCK MOUNT CRANE 8732315
Page 13 www.princessauto.com / 1-800-665-8685

WARNING! Dynamic shock loads are created by quick opening and
closing of the release valve when lowering the load. The resulting
overload may cause the hydraulic system to failure, which could result
in severe personal injury and/or property damage.
Inspect the crane at the beginning of the day before lifting. Any defects or
problems should be corrected before use.
The crane has two options for lifting and moving cargo: by hydraulic jack or by
manual winch. You can use them together or separately to lift a load.
1. Determine the load’s weight.
2. Adjust the boom extension position to 1,000 lb or 2,000 lb, based on the
load’s weight. Reinsert the bolt and secure with the washers and nut used
during assembly. The weight capacity of the boom arm is written next to
each bolt hole on the boom.
3. Position the vehicle so the crane can reach the load. Do this after
adjusting the boom extension arm in the previous step.
4. Keep the vehicle as level as possible during operation and always lift the
load straight up.
5. Loosen the base handle and rotate the crane until it is over the load.
6. To prevent the boom from swinging freely, always tighten the base handle
before lifting a load, after the load is positioned or when storing the crane
after use.
7. Always use outriggers (jack legs) from the truck to the ground. Be sure
these are rm and adequately positioned.
RAISING A LOAD
1. Close the release valve. Insert the slotted end of the handle over the valve
and twist to the right.
2. Insert the handle (#16) into the bottle jack's receiver.
3. Pump the handle until the load reaches the desired height.
LOWERING A LOAD
WARNING! Dynamic shock loads are created by quick opening and
closing of the release valve when lowering the load. The resulting
overload may cause the hydraulic system to failure, which could result
in severe personal injury and/or property damage.
WARNING! Before lowering the load, ensure that there are no
obstructions underneath and that all people are standing clear.
8732315 TRUCK MOUNT CRANE V1.0
www.princessauto.com / 1-800-665-8685 Page 14

1. Insert the slotted handle end over the release valve.
2. Open the release valve by slowly rotating the handle counterclockwise.
The load will descend as pressure is released from the jack’s system.
Control the speed by rotating the handle.
a. Rotate the handle counterclockwise to increase the speed.
b. Rotate the handle clockwise to decrease the speed.
3. Open the release valve fully once the ram has fully retracted.
4. Position supports, like jack stands, if the load will remain above ground
for an extended period. Consult the support device's manual for proper
placement.
5. Once the supports are carrying the load, open the valve to allow the ram
to retract fully.
6. When the work is done, raise the load enough with the jack to carefully
remove the supports.
HAND WINCH OPERATION
WARNING! Do not release the handle when the ratchet mechanism is
disengaged and there is a load on the line. The load will drop and can
cause a serious impact injury. The crank handle will also spin and can
cause a minor impact injury. Maintain a rm grip while unwinding until
the load is settled and there is slack in the wire rope.
The ratchet lever has 2 positions. The upper position is for winding the wire
rope onto the drum with the ratchet in gear. The lower position disengages the
ratchet pawl allowing the drum to freewheel in either direction.
WINDING/UNWINDING (NO LOAD)
1. Rotate the handle slightly to release pressure on the pawl.
2. Push the ratchet lever down until it clicks to disengage the ratchet
mechanism.
3. The drum can move freely in both directions.
4. Grasp the hook and pull the wire rope until the hook can be attached to
the load.
• Be careful as the crank handle will rotate freely and can cause an
impact injury if it strikes you.
5. Rewind any excessive wire rope by turning the crank handle. Make sure
the rope winds evenly onto the drum.
V1.0 TRUCK MOUNT CRANE 8732315
Page 15 www.princessauto.com / 1-800-665-8685

WINDING UNDER LOAD
1. Move the ratchet lever into the upper position to engage the pawl.
2. Turn the crank handle to wind the wire rope evenly onto the drum. The
pawl will click as it catches the drum's cog.
3. Continue turning the handle until the load is high enough to clear any
obstacles.
UNWINDING UNDER LOAD (LOWERING, UNLOADING)
1. Hold the crank rmly, then push gently to relieve tension on the ratchet
lever.
2. Push the ratchet lever down until it clicks to disengage the ratchet
mechanism.
3. Turn the crank handle to unwind the wire rope until the load has settled
and there is slack in the line.
4. You may need to stop the unloading task at some point. Hold the load in
place and re-engage the ratchet system. Then turn the crank handle to
raise the load until you hear the pawl click. Gradually ease pressure on the
handle until you are sure the pawl is locked in place.
5. The wire rope should be fully retracted again after use.
OPERATING THE CRANE
1. Before lifting, set the boom to the lowest practical position that will allow
your load to safely clear any objects in the swing path.
2. Attach a hook to the lift point on the load.
3. Follow the instructions for Raising A Load with the winch and jack.
4. Begin pumping the handle to raise the boom with the jack. Stop when
hook is in position, but not bearing the load's weight.
5. Check that the hook is in the best position to raise the load without it
shifting.
6. Ensure all bystanders are out of the way in case the load slips or shifts.
7. Once the load is near the boom, attach the other hook for additional
safety.
8. Continue raising the boom until the load is high enough to clear any
obstacles. Remove the jack handle and set aside.
9. Loosen the base handle and move the load slowly to the desired spot with
the crane handle.

www.princessauto.com / 1-800-665-8685 Page 16

10. Tighten the base handle once the load is in position for lowering.
11. Depending on the location, you may choose to lower the load by either
lowering the boom or reversing the winch.
12. Insert the jack handle end over the relief valve.
13. Open the release valve by slowly rotating the handle counterclockwise.
This will open the pressure valve and the boom arm will lower. Never
open or close the valve abruptly, as it may damage the jack and endanger
personnel in the work area. Control the speed by rotating the handle.
14. Lower the load the rest of the way with the winch, if needed.
15. Once the load is safely in the vehicle or on the ground, release enough
pressure to remove the hook.
16. Store the crane once all lifting operations are complete. No part of the
crane should stick out of the vehicle and the boom should be fully
lowered.
a. Slide the boom extension fully into the boom and secure with the
bolt.
b. Swing the crane into position for travel.
c. Tighten the base handle to secure the crane in place.
d. Lower the boom fully.
e. Return the jack handle to the storage bracket on the main post
f. Wind the slack wire rope onto the winch drum and engage the
ratchet lever.
CARE & MAINTENANCE
1. Maintain the tool with care. A tool in good condition is ecient, easier to
control and will have fewer problems.
2. Inspect the tool components periodically. Repair or replace damaged or
worn components. Only use identical replacement parts when servicing.
3. Keep the tool handles or gripping surfaces clean and dry.
4. Maintain the tool’s labels and name plates. These carry important
information. If unreadable or missing, contact Princess Auto Ltd. for
replacements.
5. Have a qualied technician inspect the jack:
V1.0 TRUCK MOUNT CRANE 8732315
Page 17 www.princessauto.com / 1-800-665-8685

a. Once a year.
b. After receiving a shock load. Take the jack out of service until the
technician certies that it is safe to use.
WARNING! Only qualied service personnel should repair the tool. An
improperly repaired tool may present a hazard to the user and/or others.
HYDRAULIC RAM MAINTENANCE
Monthly maintenance is recommended for the hydraulic ram. Any restrictions
due to dirt, rust, etc. can cause the either slow movement or extremely rapid
jerks, damaging the internal components. The following steps are designed to
keep the pump maintained and operational.
1. Lubricate the cylinder and the pumping mechanism with light oil.
2. Visually inspect for cracked welds, bent, loose, missing parts or hydraulic
oil leaks.
3. Inspect the hydraulic ram immediately if it was subjected to an abnormal
load or shock load.
4. Remove any hydraulic jack from service that is damaged, worn down or
operates abnormally, until repaired by an authorized service technician.
5. Check and maintain the ram oil level.
6. Always store the hydraulic ram in the fully retracted position. This will
help protect critical areas from corrosion.
7. Do not use brake or transmission uids or regular motor oil as they can
damage the seals. Always purchase and use products labeled Hydraulic
Oil.
REFILL THE HYDRAULIC JACK
The pump may become less ecient when the hydraulic oil level is too low or
contaminated by metal particulate through normal wear-and-tear.
1. Retract the ram and remove the oil ller plug.
2. Check and maintain the ram oil level.
• Check the oil level with the oil dip stick. Use a long plastic cable tie
as a substitute if the unit does not have a dipstick.
3. Fill the cylinder with a high quality hydraulic jack oil, up to the oil plug
opening.
a. Place a funnel into the oil ll neck. The funnel opening should be
wide enough to prevent the oil from collecting in the funnel’s cone.
8732315 TRUCK MOUNT CRANE V1.0
www.princessauto.com / 1-800-665-8685 Page 18

b. Pour oil into the funnel. Allow the oil to settle for one minute and
