SAFETY INFORMATION AND WARNINGS
NEVER GO BENEATH THE DOCK LIFT FOR ANY REASON UNLESS THE PLATFORM
AND HINGED BRIDGE(S) ARE PROPERLY SUPPORTED (SEE “Figure 10: How to Support
the Dock Lift for Maintenance” on page 15) AND THE POWER IS DISCONNECTED,
PROPERLY TAGGED AND LOCKED OUT. IT IS THE RESPONSIBILITY OF THE OWNER
TO ENSURE THAT NO LOAD OR TRAFFIC IS PLACED ON THE PLATFORM WHILE THE
MAINTENANCE STAND IS ENGAGED. THE CONSTRUCTION OF THE MAINTENANCE
STAND IS INTENDED TO SUPPORT THE WEIGHT OF THE UNLOADED DOCK LIFT ONLY.
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death
or serious injury.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
CAUTION, used with the safety alert symbol, indicates a potentially hazardous situation which,
if not avoided, could result in minor or moderate injury.
NOTICE is used to address practices not related to personal injury.
READ THESE SAFETY PRACTICES BEFORE INSTALLING, OPERATING OR SERVICING
THE DOCK LIFT. FAILURE TO FOLLOW THESE SAFETY PRACTICES MAY RESULT IN
PROPERTY DAMAGE, BODILY INJURY OR DEATH.
THE OPERATION OF THIS EQUIPMENT IS SUBJECT TO CERTAIN HAZARDS THAT CAN BE PROTECTED
AGAINST ONLY BY THE EXERCISE OF CARE AND COMMON SENSE AND NOT BY MECHANICAL MEANS. IT IS,
THEREFORE, ESSENTIAL TO HAVE COMPETENT, QUALIFIED OPERATORS TRAINED IN THE SAFE OPERATION
AND CARE OF THIS TYPE OF EQUIPMENT. ALL PERSONNEL MUST COMPLETELY UNDERSTAND THIS SAFETY
INFORMATION BEFORE WORKING ON OR NEAR THIS EQUIPMENT.
IT IS THE RESPONSIBILITY OF OTHERS TO ENSURE THE PROPER MOUNTING OF ANY
WALL MOUNTED EQUIPMENT SUCH AS REMOTE POWER UNITS, CONTROL PANELS
AND LIGHT PACKAGES AND TO ENSURE THAT THE MOUNTING SURFACE IS CAPABLE
OF FULLY SUPPORTING THE LOADS GENERATED BY THE EQUIPMENT.
1. Before loading/unloading the truck, ensure the trailer is in position rmly against both of the dock bumpers or bollards
and CHOCK THE TRUCK WHEELS to eliminate the possibility of the truck rolling or inching forward.
2. NEVER EXCEED THE MAXIMUM RATED CAPACITY OF THE DOCK LIFT. (i.e. The maximum load for a 6,000
lb. rated unit is 6,000 lb. with the load center at the center of the platform.) The single axle load capacity across the
ends is 75% of the rated capacity. The single axle load across the sides is 50% of the rated capacity. Refer to the
specication plate (See “Figure 2: Safety Label and Decal Locations” on page 3) for each dock lift’s particular
rating.

3. Never stand between the dock and a truck.
4. Return the dock lift to the stored position before allowing truck to depart.
5. When not in use, the unit MUST be in the fully lowered position.
6. Dock lifts must be lagged to the oor.
7. Do not apply shock loads to the unit. (I.e. Do not drop loads onto the platform, lower loads onto the platform at a high
rate of speed, stop unit abruptly or jog in lower range of travel.)
8. The platform surface must be kept clean and free from oil, debris, etc. Keep debris, etc. from underneath the unit.
9. Keep any obstructions and personnel clear of the dock lift and load and their operating path to eliminate injury and/or
damage. Avoid or eliminate any and all potential pinch points.
10. Prior to each use, ensure dock lift and load does not create pinch points during operation when located adjacent to or
near other equipment or structures.
11. Never use the unit for raising personnel unless it has been suitably designed and manufactured for that purpose by
Pentalift Equipment Corporation. Guard rails and access chains must be used.
12. Anyone using or in the vicinity of this equipment must wear protective footwear with steel toes.
13. It is the owner’s responsibility to ensure protection is provided for the operator (i.e. access chains) to prevent falling
off of the dock lift when the unit is above ground/oor level.
14. All electrical, hydraulic and/or pneumatic lines must be carefully routed to prevent them from being pinched or
severed.
15. Regular inspection and maintenance must be performed to keep the equipment in proper operating condition.
Pay particularly close attention to all hoses and/or wires in order to detect possible cracks or wear. Always follow
the instructions as per the `HOW TO SUPPORT THE DOCK LIFT DURING ROUTINE MAINTENANCE AND
INSPECTION’ section in this manual (See page 15) prior to performing any activity within the operating path of the

OWNER RESPONSIBILITY
The Owner's Responsibilities include the following:
1. The owner should recognize the inherent danger of the interface between dock and transport vehicle. The Owner must,
therefore, train and instruct operators in the safe use of dock levelling devices.
2. When a transport vehicle is positioned as closely as practicable to a dock levelling device, there shall be at least 4” (100 mm) of
overlap between the front edge of the Hinged Bridge and the edge of the oor or sill of the transport vehicle.
3. Nameplates, cautions, instructions and posted warnings shall not be obscured from the view of operating or maintenance
personnel for whom such warnings are intended.
4. Manufacturer’s recommended periodic maintenance and inspection procedures in effect at date of shipment shall be followed,
and written records of performance of these procedures should be kept.
5. Removal from Service: Any lift not in safe operating condition such as, but not limited to excessive leakage, missing
rollers, pins or fasteners, any bent or cracked structural members, cut or frayed electric, hydraulic or air lines, damaged
or malfunctioning controls or safety devices, etc. shall be removed from service until it is repaired to Pentalift Equipment
Corporation’s standards.
6. Pentalift Equipment Corporation shall supply replacement nameplates, caution or instruction labels and operating and
maintenance manuals upon request of the owner. The owner shall see that all nameplates and caution and instruction
markings or labels are in place and legible and that the appropriate operating and maintenance manuals are provided to users.
7. Modications or alterations of dock levelling devices shall be made only with written permission of Pentalift Equipment
Corporation. Alteration permission must be signed by both the Pentalift Post Sale Customer Service Manager and the
President to be valid.
8. When industrial trucks are driven on and off transport vehicles during the loading and unloading operation, the brakes on the
transport vehicle shall be applied and wheel chocks or positive restraints that provide the equivalent protection of wheel chocks
engaged.
NOTE: It is recognized that these devices are intended to secure a transport vehicle to a loading dock by mechanical means.
However, no standards currently exist for the strength, construction or attachment of the under ride guard on a transport vehicle. It
is therefore recommended that users of such positive restraint devices review:
• The means of attachment to the transport vehicle
• The strength of the overall connection
• The proper coordination of the actuation of devices with any signalling system used
• The need to use wheel chocks
9. In selecting dock levelling devices, it is important to consider not only present requirements, but also future plans or adverse
environments.

INSTALLATION INSTRUCTIONS
DO NOT INSTALL, OPERATE OR SERVICE THIS PRODUCT UNLESS YOU HAVE READ
AND FULLY UNDERSTAND THE ENTIRE CONTENTS OF THIS MANUAL. FAILURE TO
DO SO MAY RESULT IN PROPERTY DAMAGE, BODILY INJURY OR DEATH.
IMPORTANT
PREPARATION PRIOR TO INSTALLATION
Perform installation instructions in the same sequence as they are listed below.
1. Ensure pit conforms to appropriate Pentalift pit drawing. Ensure drain, if required, is in place prior to installing the
dock lift.
2. Make sure the installation surface is clean, level
and at before installing the unit. A slight slope
from clevis end to roller end is not a problem,
but a side to side slope will cause premature
wear on all moving parts of the lift. Tighten the
lag bolts.
3. The installation surface must be capable of
supporting any loads that will be applied to it.
4. Connect the two hydraulic hoses to the
hydraulic hoses sticking out on the xed end of
the frame.
Hoist the dock lift into the pit. At the same time,
feed the hydraulic hose through the conduit
from inside the pit toward the power unit. (See
“Figure 3: Moving the Dock Lift” on page 4)
5. Mount the power unit in the desired location
and connect the two hydraulic hoses. Ideally,
the reservoir should be mounted on a wall
approximately 6 1/2 feet above the ground.
BEFORE DOING ANY INSTALLATION, MAINTENANCE, INSPECTION OR TROUBLE
SHOOTING, BARRICADE ALL AREAS FROM TRAFFIC AROUND THE WORK AREA
INSIDE (& OUTSIDE IF APPLICABLE) FOR SAFETY, POST APPROPRIATE WARNING
SIGNS AND BE CERTAIN THAT THE POWER IS DISCONNECTED, PROPERLY TAGGED
AND LOCKED OUT. ALL ELECTRICAL WORK MUST BE PERFORMED BY A QUALIFIED
ELECTRICIAN IN ACCORDANCE WITH ALL APPLICABLE CODES.
MAKE SURE LIFTING AND SLINGING DEVICES ARE OF SUFFICIENT CAPACITY,
USED IN THE CORRECT MANNER AND ARE IN GOOD WORKING ORDER. ALL
LIFTING, POSITIONING AND INSTALLATION, AS WELL AS THE BREAK-IN AND
PERFORMANCE CHECK MUST BE DONE BY QUALIFIED PERSONNEL TRAINED AND
EXPERIENCED IN NECESSARY SAFETY PROCEDURES.

This prevents personnel from standing upon or placing objects on the power unit.
Run the hydraulic lines from the power unit to the lift and ush with clean uid before connecting the lines. If the lines
must be pushed through chases or enclosures, be sure to cap the lines to prevent contaminates from entering the
hose. Cleanliness is important in the maintenance of any hydraulic system.
6. Remove all shipping bolts and hardware. (See “Figure 3: Moving the Dock Lift” on page 4).
7. Connect the appropriate supply voltage to the motor control panel. (Refer to the WIRING DIAGRAM located inside
the motor control panel and the electrical specication label located on the side of the motor control panel).
NOTE: All wiring must be performed by a qualied electrician in accordance with all applicable codes.
NOTE:
a. On 3 phase units ensure phase polarity is correct. Incorrect polarity will cause the dock lift not to raise. The
motor will run backwards resulting in cavitation and possible damage to the pump.
b. To prevent tripping the motor overload relay, the motor requires the specied voltage at the motor while the
motor is working under full load. If there is a problem, conrm that the supply conductors are sufcient in relation
to the run length. See Electrical Reference Chart. (Follow all applicable electrical codes as well.)
Ensure that the thermal overload relay is set to match the full load current as shown on the motor name plate. Follow all
applicable electrical codes.

Figure 4: Square the Dock Lift in the Pit
SELF CONTAINED POWER UNITS:
If the power unit is self-contained, ensure the temporary wire is routed out of the pit for easy hook-up.
NOTE: The temporary wires supplied are intended to be used for lifting the platform for the initial installation
only. Once the maintenance stand is in position, the temporary wires are to be removed from both the power
supply and the dock lift. Permanent wiring must be installed immediately.
NOTE: The temporary wires should be connected only if they meet the requirements of the applicable local
electrical codes. If they do not, the electrician should rewire to meet all applicable codes prior to applying any
electrical power.
9. Square the dock lift platform in the pit; leaving approximately 1” space all around the pit edge.
NOTE: If the unit is equipped with a roll-off stop, the platform must be squared evenly on the two sides and offset by
11” on the xed end (See “Figure 4: Square the Dock Lift in the Pit” on page 9).
10. Raise the unit to its maximum height and then fully lower. Repeat the cycle a minimum of three times. This allows the
table to realign itself after shipping.
11. Re-check the unit to ensure it is square in the pit.
12. If required, level the unit on both sides by shimming under the four lag locations, the full length and width of the roller
travel and the lower xed end clevises. (See “Figure 5: Shim Beneath the Fixed End Clevises and Full Roller Travel”
on page 10)
13. Fully raise the dock lift and block the scissor mechanism following the instructions in HOW TO SUPPORT THE
DOCK LIFT DURING ROUTINE MAINTENANCE AND INSPECTION. (See page 15)
14. When installing into a concrete pit, lag the unit to the pit oor with recommended fasteners, 5/8” Dia. x 4 ½” long
wedge anchors with a minimum shear value of 12,900 lbs. (5 850 kg), and tension value of 10,200 lbs. (4 630 kg).
(See “Figure 5: Shim Beneath the Fixed End Clevises and Full Roller Travel” on page 10) Torque to manufacturer
specications. If the mounting surface is not concrete, utilize a fastener to suit the structural values indicated and
appropriate for the mounting surface.
15. Weld all shims together and then to the dock lift frame.

16. Install the guard rails as shown in “Figure 6: Guard Rail Installation” on page 11.
In some applications such as full depth pits, platform mounted guard rails can create a potentially hazardous
condition by creating a pinch point between the guard rail horizontal bars and the edge of the pit oor. It may be
necessary to provide protection around the perimeter of the pit. Consult applicable safety and building codes.
It is the owner’s responsibility to ensure protection is provided for the operator (i.e. access chains) to prevent
falling off of the dock lift when the unit is above ground/oor level.
17. Check the oil in the power unit reservoir and add if necessary (See “MAINTENANCE AND LUBRICATION” on
page 16)
18. Clean up any debris and/or spilled oil from the area. Check all hydraulic ttings for leaks.
19. INITIAL SET-UP: It is important to purge air from the hydraulic system. To do this, raise the unit to its maximum
raised height and allow the power unit to run for a minimum of 30 seconds additional time. Fully lower the unit.
Discontinue use of the unit for 20 minutes to allow air to dissipate from the oil in the reservoir.
NOTE: Units equipped with an up travel limit switch will not reach their “maximum raised height” unless the limit
switch is removed. The up travel limit switch must be removed to purge the air. DO NOT remove the
up travel limit switch until rst assuring there are no obstructions in the operating path of the
equipment. After the air has been purged, lower the Dock Lift to its desired raised height and reinstall the
limit switch.
NOTE: At the completion of the installation ensure that all labels are and will continue to be readily visible to
the operators and people working with or around the equipment. If the visibility any of the label(s) are
compromised for any reason then; either 1) Rectify the situation to allow the label to be readily visible 2)
Order replacement label(s) from Pentalift for installation in a location that does facilitate complete visibility.

BREAK-IN AND PERFORMANCE CHECK
NOTE: IN SOME CASES THERE IS A CONSIDERABLE AMOUNT OF TIME BETWEEN THE SHIPMENT DATE AND
USE OF YOUR DOCK LIFT. THIS INITIAL BREAK-IN AND PERFORMANCE CHECK SHOULD BE PERFORMED
BEFORE YOU BEGIN REGULAR USE OF YOUR DOCK LIFT TO ENSURE THAT IT IS OPERATING PROPERLY.
BEFORE DOING ANY ELECTRICAL WORK, BE CERTAIN THAT THE POWER IS
DISCONNECTED WITH A FUSED DISCONNECT, PROPERLY TAGGED AND LOCKED
OUT. FUSED DISCONNECT AND LOCKOUT DEVICE (SUPPLIED AND INSTALLED
BY OTHERS) MUST MEET WITH ALL APPLICABLE CODES AND REGULATIONS.
ALL ELECTRICAL WORK MUST BE PERFORMED BY A QUALIFIED ELECTRICIAN IN
ACCORDANCE WITH ALL APPLICABLE CODES AND REGULATIONS.
ARC FLASH AND SHOCK HAZARD PPE (PERSONAL PROTECTION EQUIPMENT)
REQUIRED. DE-ENERGIZE EQUIPMENT BEFORE WORKING ON OR INSIDE. DO
NOT OPEN COVER WITHOUT APPROPRIATE PPE. REFER TO NFPA 70E FOR PPE
REQUIREMENTS. THIS PANEL MAY CONTAIN MORE THAN ONE POWER SOURCE.
HAZARDOUS VOLTAGE WILL CAUSE SEVERE INJURY OR DEATH.
NEVER GO BENEATH THE DOCK LIFT FOR ANY REASON UNLESS THE PLATFORM
AND HINGED BRIDGE(S) ARE PROPERLY SUPPORTED (See “Figure 10: How to Support
the Dock Lift for Maintenance” on page 15) AND THE POWER IS DISCONNECTED,
PROPERLY TAGGED AND LOCKED OUT. IT IS THE RESPONSIBILITY OF THE OWNER
TO ENSURE THAT NO LOAD OR TRAFFIC IS PLACED ON THE PLATFORM WHILE THE
MAINTENANCE STAND IS ENGAGED. THE CONSTRUCTION OF THE MAINTENANCE
STAND IS INTENDED TO SUPPORT THE WEIGHT OF THE UNLOADED DOCK LIFT ONLY.
BEFORE DOING ANY INSTALLATION, MAINTENANCE, INSPECTION OR TROUBLE
SHOOTING, BARRICADE ALL AREAS FROM TRAFFIC AROUND THE WORK AREA
INSIDE (& OUTSIDE IF APPLICABLE) FOR SAFETY, POST APPROPRIATE WARNING
SIGNS AND BE CERTAIN THAT THE POWER IS DISCONNECTED, PROPERLY TAGGED
AND LOCKED OUT. ALL ELECTRICAL WORK MUST BE PERFORMED BY A QUALIFIED
ELECTRICIAN IN ACCORDANCE WITH ALL APPLICABLE CODES.
1. Ensure that any specied interlocks (e.g. overhead doors, restraints) are fully functional.
2. It is important to purge air from the hydraulic system. To do this, raise the unit to its maximum raised height and allow
the power unit to run for a minimum of 30 seconds additional time. Fully lower the unit. Discontinue use of the unit for 20
minutes to allow air to dissipate from the oil in the reservoir.
NOTE: Units equipped with an up travel limit switch will not reach their “maximum raised height” unless the limit switch is
removed. The up travel limit switch must be removed to purge the air. DO NOT remove the up travel limit switch
until rst ensuring there are no obstructions in the operating path of the equipment. After the air has been
purged, lower the dock lift to its desired raised height and reinstall the limit switch.
3. Raise the dock lift and install the maintenance stand as outlined on page 15.
4. Inspect hydraulic system for leaks, especially at ttings and hose connections.
5. Dock Lifts do not require lubrication of the pivot points. For ease of maintenance, lifetime lubricated bushings have been
used on all rollers, leg pivot points as well as the upper cylinder pivot. However, units installed outdoors or in wet and dirty
environments should be lubricated. See the Maintenance and Lubrication Section, page 16.
6. Ensure the toe sensor (if equipped) is functional.
NOTE: The toe sensor option is an electrical safety device with an actuator suspended beneath the platform which halts
downward travel of the dock lift if it contacts with an obstruction.
NOTE: This feature is not functional in the event of hydraulic failure.
7. Completely raise and lower the dock lift three times.
As the performance test is being conducted, watch closely for any signs that the dock lift
might not be operating properly. If you are in doubt, refer to Operating Instructions on page
13 and Troubleshooting Guide on page 19 or contact your Pentalift representative.
NOTE: Read the SAFETY INFORMATION AND WARNINGS before operating the dock leveler. (See page iii)

OPERATING INSTRUCTIONS
USE BY UNTRAINED PEOPLE CAN RESULT IN PROPERTY DAMAGE, BODILY INJURY
OR DEATH. READ, KNOW, AND OBEY ALL OPERATING INSTRUCTIONS AND SAFETY
INFORMATION. FOLLOW ALL OSHA REGULATIONS REGARDING THE USE OF THIS
EQUIPMENT. DO NOT USE THE DOCK LIFT IF ANY PART OF IT LOOKS BROKEN OR
IF IT DOES NOT SEEM TO OPERATE PROPERLY. IF REPAIRS ARE NEEDED, CONTACT
YOUR PENTALIFT REPRESENTATIVE.
DO NOT INSTALL, OPERATE OR SERVICE THIS PRODUCT UNLESS YOU HAVE READ
AND FULLY UNDERSTAND THE ENTIRE CONTENTS OF THIS MANUAL. FAILURE TO
DO SO MAY RESULT IN PROPERTY DAMAGE, BODILY INJURY OR DEATH.
1. NEVER EXCEED THE MAXIMUM RATED CAPACITY OF THE DOCK LIFT. (i.e. The maximum load for a 3,000 lb.
rated unit is 3,000 lb. with the load center at the center of the platform.) Typically, the single axle load capacity across
the ends is 75% of the rated capacity. The single axle load across the sides is 50% of the rated capacity. Refer to
the specication plate (See “Figure 2: Safety Label and Decal Locations” on page 3) for each dock lift’s particular
rating.
NOTE: The load is dened as the entire weight applied to the platform of the dock lift including all loading/unloading
equipment, etc. If you are unsure in any way as to the suitability of this product to your application, consult a
Pentalift representative prior to using the dock lift.
2. Do not apply shock loads to the unit. (I.e. Do not drop loads onto the platform, lower loads onto the platform at a
high rate of speed, stop unit abruptly or jog in lower range of travel.) Do not load or unload the dock lift while it is in
motion. Properly secure all loads.
3. Keep any obstructions and personnel clear of the dock lift and load and their operating path to eliminate injury and/or
damage. Avoid or eliminate any and all potential pinch points.
4. Prior to each use, ensure dock lift and load does not create pinch points during operation when located adjacent to
or near other equipment or structures.
5. Never use the unit for lifting personnel unless it has been suitably designed and manufactured for that purpose by
Pentalift Equipment Corporation. Guard rails and access chains must be used.
6. The platform surface must be kept clean and free from oil, debris, etc. Keep debris, etc. from underneath the unit.
7. When not in use, the platform should be in the lowered position with the hinged bridge(s) in an upright vertically
stored position with the hinged bridge chain(s) engaged. (See “Figure 7: Hinged Bridge in Vertically Stored Position”
on page 14 and “Figure 8: Hinged Bridge Not Properly Secured (See Figure 7)” on page 14).
8. To raise the dock lift, ensure the hinged bridge(s) are in the vertically stored position. Push and hold the “UP” button.
Allow the dock lift to rise to the desired height and then release the button.
9. Carefully lower the hinged bridge(s) onto the truck bed.
Prior to placing any load on the hinged bridge(s), the hinged bridge(s) must be properly
supported by a surface suitable of supporting the minimum of the equivalent of the rated
capacity of the lift for the entire width of the hinged bridge (for example: TRUCK BED,
FACILITY FLOOR OR FACILITY DRIVEWAY). A minimum of 4 inches hinged bridge penetration is required to be at all
times. (See “Figure 9: Hinged Bridge must Extend a Minimum of 4” onto the Truck Bed” on page 14) The hinge stop
and hinged bridge chains are not intended to support any weight in addition to the unload hinged bridge(s). No loads
are to be placed on the hinged bridges when they are positioned by the hinged bridge chains and/or the hinged bridge
hinge stops and not properly supported.
10. To lower the dock lift, return the hinged bridge(s) to the vertically stored position. Push and hold the “DOWN” button
and the unit will descend to its lowered position.
