TROUBLESHOOTING

Do not use to lift personnel. Do not sit or stand on
forks.

Do not climb on mast or put a side load on mast.
Do not use unit to support ladders for climbing or
hoisting.

Do not use unit outside in thunder, lightning, or
severe weather.

Wear proper clothing. Hard hat, safety shoes and
gloves should be worn as a precaution when
operating this lift.

Avoid horseplay around equipment, and keep bystanders at a
safe distance. Do not allow children to operate this unit and
always keep them out of work areas.

Do not misuse the lift. Perform only the functions for which the
lift was designed.

Never use two lifts in tandem to lift a load that exceeds the
capacity of a single lift.

Prior to each use of the unit, inspect all moving parts and the
lifting strap to ensure they are in proper working condition.

PROBLEM CAUSE SOLUTION

Masts not rising in
succession

Load is easing down
slowly

You have checked the
winch and the brake
does not work at all.

The winch is hard to
crank down.

If none of these
solutions seem to fix the
problem...

NOTE: Mast sections may rise out of succession when load is near maximum
capacity. If this occurs, the masts will correct themselves during continued use or
when the load is removed from the forks. Movement of the mast sections will not
affect the position of the forks. The carriage must elevate to the top of the top mast
section before any mast sections begin to rise, and it should lower last.

General Maintenance:

1. Check the winch handle for wear or bends.

2. Examine all bolts and nuts to be sure they are tight.

3. Legs, forks, braces and base should be dent free and damage free.

4. Check for damage (indentations) which can restrict the rotation of the
Load Cable.

5. Make sure Load Cable is seated flat and has no twists or kinks restricting
rotation.

7. Check legs by sliding them into each position to check locking mecha­nism.

8. Inspect masts and carriage hold-down device.

9. Raise mast sections to inspect for free, smooth sliding action. Make sure
slideways are free of dust and oxidation and spray a light coat of silicone
lubrication in slideways.

10. Make sure caster wheels and 8” transport wheels rotate freely and are

undamaged.

11. Check to be sure that all mast covers are attached to the lift.

OPERATING PROCEDURE

1. Moving Lift to Work Area (No Load)

The lift is normally moved to the job site by tilting back and rolling
on its 6” tires. Note: Do not pull by the lifting cable.

2. Moving Lift in Work Area (With Load)

Although it is best to move the unit to the job site unloaded, light
loads may be transported as long as the unit is rolled on the
casters and transport wheels on a level surface. Always have
the load in the lowest possible position before moving the unit.

CAUTION

If a load is being transported, it should be secured
to the forks to avoid shifting.

WARNING

Moving the unit with elevated loads should be
contained to short distances; i.e., 10-15 feet/4-5
meters.

WARNING

Replace all worn or damaged parts only with
Sumner parts.

WARNING

Modifying the lift in any way can cause injury or
death!

16

If it is necessary to move the unit with an elevated load:

 Make sure the area is clear of obstructions
 Keep personnel away from the load and behind the

operator’s position

 Move the unit slowly, avoiding sudden jerky starts and stops
 Make sure the load is secure and properly balanced. Note

load capacity at given centers on page 14.

3. Lifting and Lowering Loads

Use the winch to crank forks up or
down into the desired position.

Any unstable load must be
balanced and secured to the forks
prior to lifting.

Turn winch crank clockwise to
elevate the load, while watching for
overhead obstructions. Turn winch
handle counter clockwise to lower
the load.

CAUTION

Make sure the floor surface is level.

WARNING

No riders allowed on this unit. This is
not a personnel lift and never should be
used for hoisting or moving people.

4. Removing and Reversing Forks

The forks on the 1900 series lift
are removable. Removing the
forks is recommended for storage
and is required for reversing. The
forks may be reversed to allow for
an increased lifting height.

MAINTENANCE INSTRUCTIONS

Before each use:

1. Inspect the lifting cable for frays, cuts or burns. If any damage is visible
on the lifting strap, do not use the lift.

2. Make certain winch operates freely and lifting cable is not tangled on the
winch drum.

3. Check forks, legs, and base for bends.

4. Make sure caster wheels move freely.

Recommended Inspection Every 6 Months:

1. Inspect the lifting cable for frays, cuts or burns. If any damage is visible

Raise Lower

on the lifting cable, do not use the lift.

2. Make certain winch works freely and that there are no loose or damaged
parts.

Winch Maintenance:

1. Be sure that the winch cover is on the winch.

2. Check ratchet dog and brake ratchet for wear. If any wear is visible,
replace the winch. If not, lubricate both parts with a light oil.

3. Inspect gear teeth for wear. If there is no sign of visible wear, brush
teeth with 50-wt. Motor oil.

4. For proper brake adjustment see “Troubleshooting” section on page 17.

Replacing the Lifting Strap:

1. Lower the carriage to engage the safety latch.

2. Remove the large gear cover from the winch.

3. Remove the cable anchor bolt from the top of the front mast.

4. Remove the clamp attaching the cable to the side of the winch drum.

5. Pull the old cable through the lift out the front. Make note of the direction
of the reeve.

6. Attach the new cable to the top of the front mast using the anchor bolt.

8. Re-reeve the new cable through the lift using notes taken
in step 5.

9. Attach new cable to winch drum using clamp that was

removed in step 4. Note: The cable must be fed from

the top of the winch under the left side of the drum
(looking from the back of the lift). Winding the cable
under the right side of the drum will prevent the
brake from working.

10. Wind the slack cable tightly and evenly across the load

drum.

To remove the forks, remove the two
spring pins. Slide the fork outward off
of the mounting bars. Repeat for the
other fork arm.

Reverse this procedure to install the
forks.

To invert the forks, remove the fork
arms as described above. Rotate
the fork 180 degrees and reinstall.

5. Using the Legs

The 1900 Series Lift will arrive with the legs
in the upright storage position. Before
attempting to attach the forks and use the lift,
the legs must be rotated to the operating
position.

CAUTION

Attempting to install the forks
and/or use the lift with the legs
in the storage position will
result in the lift being unstable.

14

7

To reposition the legs, lay the
lift down on a flat level surface.

Using one hand, pull the spring loaded
pin while sliding the leg out of the base
with the other hand. Rotate the leg 90°
and reinsert it into the base with one
hand while pulling the spring loaded
plunger with the other hand. Repeat
this procedure for the other leg.

The legs can be positioned
in two configurations,
narrow and wide. The
narrow configuration allows
access into confined
spaces. While not required,
the wide configuration allows for greater stability
on lifts greater than 6 ft.
