(A) must be kept to a minimum to prevent interference
between the lifting brackets and the pit walls as the
dock leveler is lowered into the pit.
2. Make sure the mounting hardware of lifting
brackets (A) is snug. The brackets should pivot
relatively freely on the mounting cap screw. DO
NOT overtighten.
3. Attach lifting chains to lifting brackets (A) and to a
lifting device (i.e., hoist or fork truck) having the
appropriate lifting capacity and reach.

INSTALLATION
NOTE:McGuire dock levelers are designed with a
nominal 1/2 in. (12.7 mm) shimming distance to allow
for pit inconsistencies.
1. Determine height of shim stack (K) for each shim
location (B) by performing the following:
a. Measure leveler frame height distance (A).
b. Measure dock floor-to-pit floor distance (H)
at each shim location (B). Write down the
dimensions obtained at each location.
c. Subtract distance (A) from distance (H) to
obtain the shim height. Repeat for each shim
location.
4. For all HP/H models, put a minimum 1/4 in. (6.6
mm) thick shim at locations (B and C).
NOTE: A 1/4 in. (6.6 mm) thick shim at locations (B
and C) is used only as a starting point. The final shim
stack height will be determined after dock leveler is
lowered into the pit.
The dock leveler is heavy. Use chains and a lifting
device with the appropriate lifting capacity and
reach. Failure to do so may result in damage to dock
leveler and/or serious personal injury or death.
IMPORTANT
The minimum size of the shim that contacts the
leveler frame (i.e., the top shim of each shim stack)
must be at least 4-1/2 x 4-1/2 in. (114.3 x 114.3
mm) to support the full width of the frame rail and to
provide a shelf for a fillet weld.
Use the thickest shim stock possible for stability and
weld penetration purposes. DO NOT use multiple
layers of 1/8 in. (3.18 mm) or thinner shim stock.
2. Using the results obtained in step 1, create the
individual shim stacks on the pit floor at locations
(B). Build each shim stack (K) using the pyramid
method (M) (preferred) or stepped method (N)
with the top shim having a minimum size of 4-1/2 x
4‑1/2 in. (114.3 x 114.3 mm) and each successive
lower shim being larger so the shims can be
welded together using a fillet weld. DO NOT use
offset method (P) or straight method (Q).
5. Using an appropriate lifting device connected to
the lifting brackets, lower dock leveler into the pit
so rear hinge frame angle (G) is tight against rear
pit curb angle (E) across full width of the leveler
frame.
6. Allow rear of dock leveler to rest on the rear shims
while keeping the front of the dock leveler level
with the dock floor.
7. For all HP/H models, add shims at front shim
locations (C) so front of dock leveler will stay
level with dock floor when leveler is resting fully
on shims.
NOTE: To assist in obtaining an accurate measurement
of distance (J), use a string (F) pulled tight across the
pit opening, directly over the shim locations.
3. Verify that each shim stack is at the correct height
by measuring distance (J) [top of shim stack (K)
to dock floor]. Distance (J) must equal the dock
leveler height (A).

8. With rear hinge frame angle (F) tight against rear
pit curb angle (G), perform/check the following:
• Pry between the platform and rear hinge frame
angle at locations (E) to make sure rear edge of
platform is parallel to the rear hinge frame angle
(F).
• Gap (D) must exist equally along both sides of
leveler so weather seal (if equipped) will not bind

rear hinge frame angle (F) as needed.
10. Allow the dock leveler to rest fully on the shim
stacks. Check that a smooth and level transition
exists between the dock floor and the dock leveler
platform. Add or remove shims as necessary until
a smooth transition is obtained.
11. If leveler cannot be squared and/or made level as
instructed in steps 8 — 10, contact Systems, Inc.
Technical Services.

slightly depending on size of dock leveler.
4111-0018 — March 2012
DO NOT weld continuously along the full length
of the rear hinge frame angle. This can put
unnecessary stress on the leveler components,
causing the leveler to malfunction and shorten the
lifespan of the affected components.
12. With the rear hinge frame angle (F) tight against
the rear pit curb angle (G), weld the rear hinge
frame angle (F) to the rear pit curb angle (G)
using a 3/8 in. (9.5 mm) flare bevel skip weld
— each weld being 6 in. (152 mm) long.
Start at each end with a 6 in. (152 mm) long
weld. Space all the other welds out evenly leaving
approximately 6 in. (152 mm) space between each
weld.
13. Weld front of dock leveler frame (B) to shims
located under the keepers, then weld the shims to
the front pit curb steel.
14. With leveler welded into place, remove the shipping
bands from around lip and leveler frame.
15.
If the platform is raised using an external lifting device
or the hydraulic system is opened to atmosphere, air
will enter into the hydraulic system.
Whenever this happens, always cycle the leveler
at least 4 times using the leveler’s own hydraulic
power system before allowing the leveler to be put
into service. This is to make sure all air is purged
from the hydraulic cylinders. Failure to do this may
result in serious personal injury or death.

shimming method. Both platform cylinder trunnions
must be solidly shimmed the entire length of the
trunnion. Make sure the trunnions are level from
side-to-side as well as from front-to-back.
20. Finish weld all shims using a fillet weld.
•
Weld all shims within each shim stack to each
other, then weld the shim stack to the leveler
frame.
•
Weld the front leveler frame shim stacks to
the front pit curb steel.

GUIDE TO WIRE SIZE
Length of Run
CAUTION: Sufficient voltage must reach the Leveler Control box to operate the 1.25HP motor.
Voltage drop caused by long wire runs or undersized wire increase the AMP draw and will cause
the breaker to trip and/or more serious damage to occur. Therefore, it is important for installation
to be done to meet all codes and done by a licensed electrician.
IMPORTANT NOTE: The values given are intended to be ONLY a guide. Be sure to check all
electrical code, local and national before installation. This chart indicates the length of branch
circuit having a 2% voltage drop at full load amps(FLA) current, at start up, in feet.
VALUES are for THIN copper wire only.

TROUBLESHOOTING
Troubleshooting
When service under the dock leveler is required,
always lock all electrical disconnects in the OFF
position after raising the platform and engaging the
maintenance prop. Failure to do this may result in
serious personal injury or death.
Always post safety warnings and barricade the
work area at dock level and ground level to prevent
unauthorized use of the dock leveler before
maintenance is complete. Failure to do this may
result in serious personal injury or death.
Always stand clear of the dock leveler lip when
working in front of the dock leveler.
The maintenance prop MUST be in the service
position when working under the dock leveler.
For maximum protection, use an OSHA approved
locking device to lock the maintenance prop in
the service position. Only the person servicing
the equipment should have the key to unlock the
maintenance prop.
Unless the dock leveler is equipped with a tethered
remote, two people are required to engage the
maintenance prop: one person to operate the unit,
the other person to engage the maintenance prop.
Failure to follow these instructions may result in
serious personal injury or death.
Before performing the detailed troubleshooting procedures, check the following items first:
• Check all fuses inside the control panel(s). Replace
any blown fuse(s) with a fuse of equal specification.
• Make sure to pull the fuses out of the circuit to test.
• Make sure the correct voltages are present at the
proper locations inside the control panel(s).

Possible Cause
Solution
Platform does not rise.
Motor does not energize.
Motor overload device
tripped or fuse blown.
Reset overload relay (three-phase) or replace fuse(s)
(single-phase). Determine cause of overload.
NOTE: When replacing fuse(s), the new fuse must
have the same specification as the old fuse.

or motor relay (single‑phase)
not energizing.
• If voltage is present and starter or relay does not
energize, replace starter or relay.
• If voltage is not present, check all components in
series with the starter or relay coil.

Symptom
Platform does not
rise. Pump operates in
pressure relief mode.
Possible Cause
Solution
Heavy object(s) on platform. Remove object(s) from platform.
NOTE:For safety reasons, the dock leveler is
designed to lift only the platform’s own weight. The
motor will continue to run which will result in melting
the reservoir.

Relief in the Adjustment section.
NOTE: The pressure relief valve must not be set at
a level that causes the motor operating current to
exceed the full load amp value* at any time, including
when operating in pressure relief.
*The full load amp value can be found on the inside cover of the
control panel.
Platform rises slowly.
Low hydraulic fluid.
Add fluid as needed. See Periodic Maintenance in the
Maintenance section.

system.
Clean and inspect valves. Flush contaminated oil
from hydraulic system. Fill system with new oil. See
Periodic Maintenance in the Maintenance section.
Damaged or restricted
hydraulic hose(s).
Replace damaged hose(s). Remove restriction.
Pressure relief set too low.
Increase pressure relief. See Adjust Main Pressure
Relief in the Adjustment section.
NOTE: The pressure relief valve must not be set at
a level that causes the motor operating current to
exceed the full load amp value* at any time, including
when operating in pressure relief.
*The full load amp value can be found on the inside cover of the
control panel.
Pump motor loads down
when platform reaches
the full raised position.
Pressure relief set too high. Decrease pressure relief. See Adjust Main Pressure
Relief in the Adjustment section.
NOTE: The pressure relief valve must not be set at
a level that causes the motor operating current to

Customer Information

NOTE: Refer to illustration for left/right orientation of
dock leveler.
The model/serial number decal (A) is located
on the left platform joist near the front (lip) of
dock leveler.
When you receive your HP/H dock leveler, write down
the dock leveler model and serial number in the form
provided. This will help ensure safe keeping of the
numbers in the event the model/serial number decal
(A) becomes lost or damaged.
Also, write down McGuire’s job number, the company
that installed the dock leveler, and the original owner’s
name. This will all help to identify the specific dock
leveler if more information is required.
When ordering, use part numbers and description
to help identify the item ordered. Do not use “item”
numbers. These are only for locating the position of
the parts. Always give dock leveler MODEL NUMBER
and/or SERIAL NUMBER.
