Operating Instructions for Optional Bench Top Style Battery Charger
(for DC models equipped with our Bench Top Charger)
WARNING!
Working with or near lead acid batteries is dangerous.
Batteries contain sulfuric acid and produce explosive gases.
A battery explosion could result in loss of eyesight or serious
burns.
Do not smoke or allow a spark or flame near batteries.
Charge batteries in locations which are clean, dry, and well
ventilated. Do not lay tools or anything metallic on top of any
battery. All repairs to a battery must be made by experienced
and qualified personnel.
When working with batteries, remove personal items
such as rings, bracelets, necklaces, and watches. A battery
can produce enough voltage to weld jewelry to metal causing
a severe burn.
Always have plenty of fresh water and soap nearby in
case battery acid contacts skin, clothing, or eyes.
Operating the battery with a low battery voltage can
cause premature motor contact failure.
Do's and Don'ts
DO NOT leave charger connected for an indefinite length
of time.
DO NOT smoke, strike a match or cause a spark in the
vicinity of battery during charging.
DO make sure all battery connections are tight and clean.
DO NOT expose to rain or adverse conditions.
DO replace defective cords and wires immediately.
DO locate charger at least 24" above floor while charging.
DO NOT overcharge battery (manual position only)
OPERATING INSTRUCTIONS

Operating Instructions for Standard On Board Style Battery Charger
(for DC models equipped with our On Board Charger)
WARNING!
Working with or near lead acid batteries is dangerous.
Batteries contain sulfuric acid and produce explosive
gases. A battery explosion could result in loss of eyesight
or serious burns.
Do not smoke or allow a spark or flame near batteries. Charge batteries in locations which are clean, dry,
and well ventilated. Do not lay tools or anything metallic
on top of any battery. All repairs to a battery must be
made by experienced and qualified personnel.
When working with batteries, remove personal items
such as rings, bracelets, necklaces, and watches. A
battery can produce enough voltage to weld jewelry to
metal causing a severe burn.
Always have plenty of fresh water and soap nearby in
case battery acid contacts skin, clothing, or eyes.
Operating the battery with a low battery voltage can
cause premature motor contact failure.
Our On Board charger is equipped with an external
ground wire (small green). During installation the charger
must be grounded to the equipment which it is connected
to. Be sure this wire is always connected to the chassis,
frame, or other metallic surface considered to be ground.
OPERATING INSTRUCTIONS
1.) Plug charger into a receptacle known to have
approximately 115V and 60 Hz. If an extension cord
must be used, keep it short and as large as possible.
A small cord will decrease the output of the charger
due to the voltage drop in the line. This will increase
the charging time.
ADDITIONAL INFORMATION
The On Board charger is current limited and will not
exceed its rated output, even if loads are placed on the
battery while the battery is charging.
The On Board chargers fuse will blow if the charger is
connected in reverse polarity
TROUBLESHOOTING
1) Make sure battery connections are electrically and
mechanically sound.
2) Check AC source for power.
3) Check fuse. Replace only with a fuse having the
same rating as originally supplied.
4.) Check battery condition. A highly sulfated battery
may take some time before current begins to flow
through it.
DO'S AND DON'TS
DO NOT leave charger connected for an indefinite length
of time.
DO NOT smoke, strike a match or cause a spark in the
vicinity of battery during charging.
DO make sure all battery connections are tight and clean.
DO NOT expose to rain or adverse conditions.
DO replace defective cords and wires immediately.
2.) When properly connected, the charge LED will
indicate the status of charge current flowing to the
battery.
3.) With only the red LED lit, the charger is providing full
output to the battery.
With both the red and green LED's lit the charger is
"topping off" the battery.
When only the green LED is on, the unit is providing a
"float" or maintenance, charge.
4.) Remember to unplug the charger before moving
equipment. Failure to do so could cause damage to
cords, receptacles and other equipment.
5
HYDRAULIC OPERATIONFOR AC/DE
When the operator wants to raise the unit, he/she depresses the UP button. This starts the electric motor
which turns the hydraulic pump. Oil from the reservoir is drawn in through the suction filter and into the pump.
The pump delivers pressurized oil through a check valve before it enters the cylinders.
The function of the check valve is to allow the oil to flow in one direction, (towards the cylinders), and prevents
the flow of oil back into the pump circuit when the pump stops running. This holds the oil in the cylinders and will
maintain any particular barrel elevation, for extended periods of time.
If the load is excessive, and the UP button is still depressed, excessive pressure will build up in the circuit
between the pump and the cylinders. This forces the relief valve to unseat allowing the pump flow to circulate to
the reservoir preventing hydraulic or structural damage.
When the operator desires to lower the unit, he/she depresses the DOWN button. This energizes the
lowering solenoid valve coil, unseating the poppet valve and allowing oil return from the cylinders through the
pressure-compensated flow control valve, to the reservoir.
Releasing the DOWN button will de-energize the solenoid, closing the valve poppet. This and the check
valve prevents the oil from returning to the reservoir and the cylinders will stop retracting. The unit will maintain
that particular elevation until the operator chooses to move it once again.
Cartridge Valves
The lowering valve, as discussed above, is of cartridge construction and is virtually maintenance-free.
If there is a faulty operation, check Trouble Shooting Section. To clean the cartridge valve, follow this procedure:
1.) WARNING! Lower forks completely before removing cartridge valve.
2.) Use a sharp object to push poppet in from the bottom to open the valve.
3.) Repeat several times while valve is immersed in kerosene or mineral spirits. Blow dry.
4.) Blow compressed air through valve while holding the valve open as described in step 2.
5.) Inspect "o" rings and the teflon washer. If either shows nicks, tears, or cuts, replace.
6.) Reinstall. The valve should be tightened to approximately 20 ft. lbs.
Velocity Fuse
There is a brass velocity fuse with a stainless steel spring in the base of each cylinder (Item 10). In the
event of a hydraulic hose or fitting failure, the platform starts to lower at a fast rate. As soon as the descent speed
exceeds the preset speed, the Velocity Fuse will shut off the oil flow and the platform will remain nearly stationary
until pressure is re-applied after repairs are done. This safety feature reduces the possibility of accidental
personal injury or damage to the table or contents. If air is introduced into the system, the velocity fuse can lock
up even though no failure has occurred. To reset the velocity fuse just activate the pump by jogging the UP button.
Remove the load and cycle the unit several times to purge air.
6
Air Bleed Procedure
If the forks descend very slowly or will not descend at all, air is likely trapped in the hydraulic circuit and must be bled from the system. The High Rise Lift Truck utilizes a bleeder screw at the top of
the cylinder. To bleed air from the hydraulic circuit, follow these directions.
1.) Loosen the bleeder screw at the to of the cylinder approximately 1/4 to 1/2 turn to allow trapped
air to escape. Depressed the foot pump treadle or job the motor to push the out of the system.
2.) When the cylinder is free of air only clear hydraulic fluid will be visible at the bleeder screw. Tighten
the hose fitting.

PERIODIC MAINTENANCE INSTRUCTIONS
WARNING! REMOVE LOAD AND COMPLETELY LOWER FORKS BEFORE PERFROMING ANY MAINTENANCE.
(A) Before Each Use Check For The Following :
1.) Frayed wires (Powered models only)
2.) Oil leaks
3.) Proper caster operation
4.) Pinched or chafed hoses, loose fittings
5.) Structural deformation of forks or frame
6.) Unusual noise or binding
Do not use if there are any of the above!
(B) Monthly Inspections
1.) Check oil level. Oil should be 1" to 1-1/2" below the top of the tank with
the lift in the fully lowered position. Add as necessary.
2.) Check for oil leaks. See Trouble Shooting Section and correct
as necessary.
3.) Check water level in battery. (DC models only)
4.) Check clevis and pivot points for wear.
5.) Check for worn or damaged hydraulic hoses, electrical wires, and cords.
Repair as necessary.
6.) Check rollers for looseness and wear. See Trouble Shooting.
7.) Check retaining rings at load rollers and clevis.
8.) Check for unusual noise. See Trouble Shooting section.
9.) Make sure all warning labels are in place and in good condition.
10.) Clean off dirt and debris.
(C) Yearly Inspection
12
Hydraulic oil should be changed at least once a year, or sooner if the
oil darkens or becomes gritty. Flush reservoir before refilling. Presence of
water is indicated if the oil turns milky. Recommended oil: Purity ISO AW-32
Hydraulic fluid or equal.
All maintenance work must be performed by qualified personnel with
training in the repair of electrical and hydraulic components.
Operating Instructions for Two-speed Hydraulic Foot Pump
Features:
Your new lift equipment has been supplied with an exclusive two-speed foot pump. The internal features of your pump
include a primary pressure relief valve, pressure compensated return flow control valve, and an integrated lowering
valve.
Replaceable bushings, valve components, and seals have been utilized in the construction of the pump in the event
that replacements are necessary.
Operating Instructions:
Stay clear of moving parts. The platform will rise as the foot pedal is pumped. Depressing the release lever will lower
the table at a controlled rate of descent.
In the event the platform has been overloaded, the pressure relief will open because of excessive pressure build-up
in the hydraulic system. Oil will bypass into the reservoir. Never change the pressure relief setting. Do not exceed
the rated capacity of your lift equipment.
Speed Selection for Two-speed Pumps:
This pump offers two "speeds". The low speed produces low volume/high pressure. The high speed produces high
volume/low pressure. The operator has the option of selecting the optimum pump speed for the application at hand.
Pump speeds are selected by sliding the "lock collar"(See item # 2A on the parts identification) in
drop of oil will keep the collar working freely.
or out. An occasional
Air Bleed Procedure:
Whether your pump is a new installation, or has been recently serviced, air has likely entered the hydraulic
system. The design of this pump includes an "air bleed screw" which will aid in the removal of unwanted air from
the foot pump area of the hydraulic system. Use the following steps to remove this air from the system.
1) Check all fittings to be sure they are tight. Ensure that the oil is filled to within 1" of the top of the reservoir
when the lift is in the fully lowered position.
2) Locate the "air bleed screw"( See item # 33 on the pump body) and loosen appoximately 1/2 turn
couterclockwise. As soon as you have loosened the screw, slowly depress the foot pedal. This will force the air
out of the pump chamber. Before you let the pump pedal return to the "up" or "home" position, tighten the air
bleed screw. This will prevent air form re-entering the pump chamber. Repeat the above procedure until the
pump chamber is completely filled with oil and a "spongy" feel is no longer present. If the air bleeding procedure
has been successful, the feel of the pump pedal will be firm and the complete stroke of the pump will produce
fluid flow.
