SECTION 1
INTRODUCTION
•
This manual attempts to provide all of the information necessary for the safe and proper installation, operation and maintenance of Presto’s Battery Operated Work Positioner. It is important
that all personnel involved with the installation,
maintenance or operation of the Work Positioner
read this manual. Additional manuals are available at www.prestolifts.com
The battery-operated Work Positioner is equipped
with a data plate that has a serial number and
model identification. Please refer to these numbers when ordering parts or requesting further
information.
The battery-operated Work Positioner is designed
for lifting, lowering and positioning a wide variety of loads. Call Presto for further instructions
where unique situations arise that are not covered
in this manual.
The battery-operated Work Positioner is designed
for only indoor, non-hazardous locations. These
units are not for personnel lifting. All equipment
is manually propelled and has a hydraulically
powered vertical travel.
SECTION 2

SECTION 3
INSTALLATION
A. INSPECTION
The lift is tested and inspected prior to shipment.
Inspect the Work Positioner completely upon receipt, to determine if there is any damage caused
during shipment by the freight company and that
the lift is complete. A freight claim must be filed
with the freight company if damage is apparent. Do Not use the lift if there appears to be any
damage. Check the following with the lift in a
collapsed position:
•
•
SAFETY
All personnel must stand clear of the lift
while in motion.
Do not put hands or feet under the forks or
platform.
Do not stand underneath the forks or platform.
Do not stand in front of the Work Positioner
while in motion.
Do not stand, sit or climb on the lift.
Do not use the lift on soft, uneven or unstable
surfaces.
Do not exceed the load center or capacity.
•
Check for signs of damage especially to the
back cabinet that houses the battery, electrical/hydraulic power pack.
Check all connections for tightness. Is there
hydraulic fluid visible?
Check base frame for dimensions and structural integrity.
Inspect for any bent or damaged metal parts.
The battery-operated Work Positioner is a very
powerful lift capable of doing large amounts of
work.
•
Carefully read this manual before installing
or operating this lift. Some hazards have been
identified that may occur during the installation,
maintenance and use of this lift.
Remove all packaging materials prior to removing the lift from the pallet. Visually inspect the
lift as closely as possible.
WARNING!
•
•
Do not perform any repair work on lifts if
there is a load on the forks or platform.
Do not perform any repair work if the forks
or platform is in the raised position.
PRESTO OWNER’S MANUAL
Page B. REMOVING FROM PALLET:
Carefully pick up the lift taking into consideration the center of gravity of the lift with an
overhead hoist or forklift. Use a hoist and nylon
sling with a minimum of 2,000-lb capacity if you
choose to pick the lift up with an overhead hoist.
WP & WPS Series Work Positioners
Pick the lift up by the top cross member of the
lift. Have all personnel completely cleared from
the area because the lift will begin to swing when
it is clear of the pallet.
Pick the lift up approximately six inches above
the pallet. Once raised and secure remove the
pallet from below the lift then lower the lift.
OPERATION
A. OPERATING INSTRUCTIONS:
1. To raise the lift, push the control handle or
activate the UP BUTTON on a remote control.
2. To lower the lift, pull the control handle or
activate the DOWN BUTTON on a remote
control.
3. Whenever the controls are released, the lift
stops.
AUTHORIZED OPERATORS SHOULD READ
AND UNDERSTAND ALL INSTRUCTIONS,
PRECAUTIONS AND WARNINGS. IMPROPER USE OF THIS LIFT COULD RESULT IN
INJURY AND/OR DAMAGE TO THE LOAD
AND/OR EQUIPMENT.
•
•
•
•
•
•
Inspect the lift for damaged or worn parts.
Do not use if not in safe operating condition.
Use lift only on hard level surfaces.
Make sure load is evenly distributed, not
loose or unstable and is as far back as possible on the platform or forks. Do not pick
up loads on the tips of the forks or edge of
platform.
Adjust forks to the maximum practical width
on a fork model lift if they are adjustable.
Pick loads up on both forks, not one.
Do not overload. Check load center and lift
weight capacities that are located on the data
plate.
Make sure work area is clear of all obstructions.
Check overhead clearance before lifting loads
or transporting.
PRESTO OWNER’S MANUAL
•
Make sure floor lock pad is in firm contact
with floor before lifting load, lowering load
or using as a workstation.
Brace or block lift when sliding loads on or
off platform or forks.
B. DAILY OPERATIONS MAINTENANCE
CHECKS:
1. Battery
• Check for corroded and loose terminals. A
white powder substance will be present if
there is any existing corrosion.
• Check for loose battery tie-downs.
• Visually inspect for any cracks or damage to
the casing.
SECTION 4
•
•
Page 2. Charger
• Inspect wire connections.
• Check power cord for nicks/damage.
• Check charger for proper mounting.
3. Hydraulic System
• Inspect pump and cylinder for oil leaks.
• Check hydraulic oil level. Unscrew breather
plug on power unit with forks platform fluid
will be ½ - ¾ of an inch from opening all the
way down.
• Check hydraulic fittings and hoses
4. Frame Assembly
• Check floor lock.
• Check placement of safety screen.
• Check chain roller assembly.
• Check for any worn or damaged parts.
SECTION 5
MAINTENANCE
A. INSTRUCTIONS:
•
•
•
Grease wheels and casters at least once a
month to maintain easy roll of lift.
Use only Hydraulic Oil (Conoco Super Hydraulic 32 or equivalent) in the hydraulic system. NEVER USE HYDRAULIC BRAKE
FLUID.
Do not overload your lift.
WP & WPS Series Work Positioners
reference.
B. MONTHLY MAINTENANCE CHECKS:
1. Battery
• Clean terminals.
• Clean battery compartment area.
• Check specific gravity -- fully charged battery
should read 1265.
• Check fluid level in all cells. Fill with
distilled water as necessary to bring fluid to
within ¾” of the top.
2. Hydraulic System
• Clean and inspect hydraulic cylinder.
• Lubricate chains with a rust inhibitive chain
lubricant.
• Check chain tension. The chains should be
tight enough so that they do not come off the
chain roller assembly. The tension should
be adjusted so that the chains bear equal
amounts of load weight.
SECTION 6
SERVICE
IF LIFT DOES NOT RISE TO FULL HEIGHT
-- check for leaks or shortage of oil. Maintain the
proper oil level.
IF THE LIFT TENDS TO CREEP DOWNWARD
UNDER A LOAD -- a speck of dirt may be
obstructing the seating of the valve and allowing
leakage. To correct, follow these instructions:
•
Raise lift to full lifting height and then lower
it to lowest point of lift. It may be necessary
to do this five or six times. In lowering the
lift, lower it in stages, that is, lower the lift
six inches to a foot at a time. This will dislodge the dirt and lift will operate properly.
3. Frame Assembly
• Clean and lubricate all roller bearings and
cam followers.
• Clean and inspect all welds.
• Check wheels for wear and damage.
• Inspect nameplate for legibility. Place the serial and model number shown on the nameplate on the cover of the manual for future
