5. AIR SUPPLY
5.1. You will require an air pressure of minimum 120psi, maximum 200psi to get the best performance from this lift.
WARNING! Ensure the air supply does not exceed 200psi 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. MT680 has a vent valve, see Fig.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.
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, see 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, see fig.5
6.1.5.3. Lower the lift by depressing the release foot pedal slowly, to control the rate of descent.
6.2. Operation (Refer to the Parts Diagram)
999 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.
6.2.1.
