5. AIR SUPPLY

5.1. You will require an air pressure of minimum 100psi, maximum 120psi to get the best

performance from this lift.

WARNING! Ensure the air supply does not exceed 120psi while operating the lift. Too

high an air pressure and unclean air will shorten the product’s life due to excessive wear,

and may be dangerous, causing possible damage and/or personal injury.

5.2. Drain the air tank daily. Water in the air line will damage the lift.

5.3. Clean the air inlet filter screen weekly.

5.4. Keep the air hose between the compressor and the lift as short as possible, and install an

air filter and oiler, (fig 2).

5.5. Line pressure should be increased to compensate for unusually long air hoses (over 8

metres). The minimum hose diameter should be 1/4” I.D. and fittings must have the same

inside dimensions.

5.6. Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all connections are secure.

6. PREPARATION FOR USE

6.1. BEFORE USE

6.1.1. This lift has a vent valve (figs.3 & 3A). This is closed for transit

only. Before use the valve must be lifted or the pump will not

function properly.

6.1.2. Let the hydraulic pump stand for one hour, to allow the oil to settle,

before purging the system.

NOTE: Failure to allow sufficient time for the oil to settle could

result in air remaining in the oil. Should the pump fail to purge

completely at the first attempt, a second purge will be required.

6.1.3. Purge the hydraulic system by depressing the release foot pedal

and pumping the lift foot pedal fifteen to twenty times.

6.1.4. Test the lift unladen by moving the safety handle to the right and

raising the lift to full height (figs.4 & 5).

6.1.5. SAFETY HANDLE OPERATION

6.1.5.1. To raise. Before raising the lift the safety handle must be moved

to the right hand side of the detent (fig.4) to prevent accidental

lowering.

6.1.5.2. To lower. Raise the lift by pumping the foot pedal several times

(or by air), to let the safety plate free from its locked position, then

move the safety handle to the left and lock it in its detent (fig.5).

6.1.5.3. Lower the lift by depressing the release foot pedal slowly, to

control the rate of descent.

7. OPERATION

WARNING! Ensure that you read, understand and apply the Section 1 Safety Instructions.

999WARNING! DO NOT overload the vehicle lift. The maximum load is 680kg.

7.1. Position the lift in a suitable location, preferably on a concrete surface.

999 WARNING! The vehicle must be fully supported by the lift platform prior to lifting. DO NOT put the rear wheel of the vehicle on the leading

plate (9) and DO NOT use the leading plate to support the weight of the vehicle when lifting. The leading plate (9) is only used to assist

the operator in wheeling the vehicle on the platform when the lift is at its lowest position.

7.1.2. Secure the vehicle to the lift platform.

7.1.3. When working on a motorcycle, wheel the bike in to the wheel clamp at the front of the lift, tighten the clamp to hold the bike in place.
