TAIL LIFT DESCRIPTION AND FEATURES
1. Description of Tail Lift
For heavy-duty and stable operation, PHE Tail Lifts come with 4-cylinders, 2-cylinders for lifting and 2
for tilting operation.
2. Lifting Cylinders (Safety feature: with hose burst valve)
The two lifting cylinders are used to raise and lower the platform. Each cylinder is fitted with a hose
burst valve, which prevents the platform being lowered if any hose burst. This will protect the
operator and also the goods on the platform.
3. Tilting Cylinders - Auto-leveling function (optional)
The two tilting cylinders are used to lift and lower the platform tip. When the platform is lowered to
reach the ground, the auto-leveling operation is activated to tilt and position itself on the ground
4. Tilting Cylinders - Manual function
Manually push button to tilt the platform to the ground.
5. Steel / Aluminum Platform
Steel
The platform welding construction is made from steel. The chequered plate rough surface will
prevent carried product from slipping away.
Aluminum
The aluminum platform have less weight compare to the steel ones. Constructed by using high
strength profiles aluminum and with anti skid surface.
6. Safety Warning Flags
PHE Tail Lift warning flags are highly visible for maximum safety, Made of high strength reflective
PVC leather for maximum durability.
7. Silent Operation
Features an electro-hydraulic power pack encased in rugged housing for silent operation.
8. Easy-to-use Controls
Features simple mounted push buttons with a built-in safety mechanism that minimizes lifting error.
Also comes with a wired remote control for an even safer and convenient operation.
9. Platform Foot Switch
Switch installed on platform that can be operated by foot. Step on the switch to lift and lower the
platform to desired level of height.
10. Warranty
Each PHE Tail Lift comes with 12 months manufacturer’s warranty to give you assurance of quality
and durability. (Terms and Conditions apply, details refers booklet Warranty Information and
Maintenance Record)

GENERAL OPERATING INSTRUCTION
•Following are some instructions for operating hydraulic equipment:
•Never work on the hydraulic system while it is under pressure.
•Hydraulic equipment should always be kept as clean as possible.
•Always clean the power pack before servicing, and always work on the unit with clean hands.
•If you wish to paint the equipment, tape off all moving parts; flexible connections and nameplate.
•Before mounting the power pack, please check for correct positioning, ambient temperature,
operating voltage, etc.
•Do not use pipe dope, tape or sealing compound as they will cause problems.
•Do not direct high pressure water to power pack when cleaning the truck.
Please check the following points;
•Check power pack for any damage during shipment.
•Check the direction of rotation of the motor. Pump will be damaged if the rotation is wrong.
•Cleanliness is very important when filling the reservoir. Use only clean and fresh hydraulic oil.
•Always recheck the oil level after using the unit and refill if necessary.
•Avoid getting air into the hydraulic system. If you do, it is very important to remove all the air from
the system.
•The air must be removed at the highest point of the hydraulic system. There is usually a relief screw.
•Energize the power pack and actuate each of the valves to be sure they are operating properly.
•Please check the operating temperature regularly. It should not increase by more than -15˚C to
+70˚C.
•Check the new power pack for any leakage after short period of time. Tighten any fittings that may
be leaking.

Operating instructions must be read and fully understood by all personnel authorized to use the PHE tail lift.
UNAUTHORIZED PERSONNEL SHOULD NEVER USE THE TAIL LIFT.
ENSURE NO PERSON OR PROPERTY IS ON RISK AT THE AREA WHERE THE
PLATFORM WILL BE OPEN.
ENSURE LOAD IS SECURED ON PLATFORM DURING LOADING/UNLOADING.
VEHICLE ENGINE MUST BE RUNNING TO OPERATE THE TAIL LIFT.
FAILURE TO COMPLY MIGHT DAMAGE THE TAIL LIFT COMPONENTS AND
EVEN VOID THE WARRANTY!
1. Disengage the tail lift
Disengage the handles on the platform before operate the tail lift.
2. Operate the tail lift
Operate the tail lift by using either side control box or remote control (that plugged into side control box) to
operate the tail lift.
3. To open the platform
Press and hold both “DOWN” and “TILT” buttons until the platform is lowered to horizontal position.
4. To lower the platform (with Auto-leveling option)
Press and hold “DOWN” button until the platform descends to required level.
When platform reaches the ground at lowering positions, it will automatically level to the ground.
5. To raise the platform (with Auto-leveling option)
Press and hold “UP” button until the platform raised to horizontal position.
6. To close the platform
Press and hold both “UP” and “TILT” buttons until the platform closes against vehicle body. Finally engage
the platform securely with handles.

7. To lower the platform (manual)
Press and hold “DOWN”button until the platform reach floor level. Followed with “DOWN” and “TILT”
buttons together to have platform lies flat on the floor.
8. To raise the platform (manual)
Press and hold “UP” and “TILT” buttons until the platform being lifted up against floor. Press and hold “UP”
button until the platform raised to horizontal position.

PRECAUTIONS IN HANDLING
The driver and operator should be well trained in proper procedure for operating the PHE tail lift.
Read through the manual BEFORE starts to operate the PHE tail lift.
1. DO NOT load the PHE tail lift more than the SWL (Safe Working Load). Refer to the tagging on tail lift
for the actual SWL.
2. Inspection and maintenance on tail lift periodically for longer service life (Please refer to
Maintenance, page 36.
3. DO NOT stand under the tail lift when it is in operation.
4. DO NOT operates the tail lift if you are intoxicated or physically exhausted. You may not able to take
the necessary emergency measures under these conditions.
5. The operator should not be physically handicapped. (Bad eyesight or hearing)
6. The load must be stabilized on the platform to avoid damage to equipment or personnel.
7. NEVER work on the hydraulic system while it is under pressure.
8. NEVER use tape, pipe dope or sealing compound on the hydraulic fittings as they will cause problems.
9. NEVER direct high pressure water on power pack during cleaning the truck. Hydraulic equipment
should be kept clean all the times.
10. If you wish to paint the equipment, tape off all moving parts, flexible connections and etch plate.
VEHICLE ENGINE MUST BE RUNNING TO OPERATE THE TAIL LIFT.
FAILURE TO COMPLY MIGHT DAMAGE THE TAIL LIFT COMPONENTS AND

ELECTRICAL FITTING
As it is preferable to be able to operate the tail lift during mechanical fitting, the electrical wiring
should be carried out first.
2.1 Heavy Duty Electric
2.1.1 Single pole wiring –connecting power cable to battery
Disconnect the live terminal from the vehicle battery, crimp or solder a terminal lug to one end
of the heavy-duty electrical cable provided. Attach the terminal lug on the cable to the terminal
lug clamp bolt on the battery live terminal, but DO NOT reconnects the battery.
Check that the existing earth lead from the battery to the chassis is at least 40mm2(300-Amp)
and does not show any signs of wear. If the lead is smaller, or is worn, replace with a new lead of
at least 300-Amp capacity.
2.1.2 Insulated earth wiring; connecting to battery
Disconnect both terminals from the vehicle battery. The heavy-duty electrical cables provided
are in 2 equal lengths. Crimp or solder terminal lug to one end of each cable. Attach the terminal
lug on the cables to the terminal lug clamp bolts on the battery terminals. DO NOT reconnects
the battery.
2.1.3 Running the cables to the rear of the vehicle
Route cables neatly to the rear of the vehicle, ensuring the cables are:
a) Well supported, safe and not vulnerable.
b) At least 50mm (2 inch) away from any brake line.
c) Well away from exhaust pipe.
d) Securely clipped and free from any chafing hazard.
e) Protected when passing through any holes, by grommet the hole.
2.2 Light Duty Electric
2.2.1 Sitting and wiring controls
Route the cable to power unit. Connect the power unit and valves as shown in respective
diagrams, using crimp terminals and sleeves supplied.
2.2.2 3-Button-Remote-Control
2.2.2 When tail lift control is required from inside the vehicle body, 3-button-remote-control
are used: this simply plugs into the control station socket.
