4. AIR SUPPLY
4.1.
You will require the air pressure detailed in the Specification section, to get the best performance from this jack.
WARNING! Ensure the air supply does not exceed the stated maximum pressure while operating the jack. 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 personal injury.
4.2.
Drain the air tank daily. Water in the air line will damage the jack.
4.3.
Clean the air inlet filter screen weekly.
4.4.
Keep the air hose between the compressor and the air jack as short as possible, and install an air filter and oiler (fig.2).
4.5.
Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter should be
3/8" I.D. and fittings must have the same inside dimensions.
4.6.
Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all connections are secure.
5. OPERATION
Refer to fig.1
5.1.
Connect air supply.
5.2.
Insert handle into handle socket.
PREPARATION
5.3.
5.3.1.
Before first use carry out the following:
(a) Check oil level: open release valve (not more than three turns) and press down on saddle to ensure piston is fully down, then
remove filler plug. Oil should be level with bottom of filler hole. Fill as necessary and replace plug.
(b) Bleed system: With release valve open, operate the manual pump for three strokes to bleed any air from the system. Close
release valve.
(c) Lubricate: Oil the pivots of the manual pump mechanism and the screw thread of the saddle post. Put two or three drops of air tool oil
into the inlet of the air valve. Connect to air supply and operate for three seconds to distribute lubricant.
(d) Air supply: an air in-line filter is recommended (fig.2).
5.4.
RAISING
5.4.1.
Ensure compliance with all safety instructions - section 1 Safety.
5.4.2.
Check that release valve is closed.
Position jack so that saddle is under vehicle jacking point. If necessary screw up saddle to just below jacking point. DO NOT use
5.4.3.
handle in the release valve to move jack - damage will result.
5.4.4.
Press the air valve trigger to raise, release trigger to stop. Alternatively use the handle to operate the manual pump.
5.4.5.
Always support the jacked vehicle on axle stands before working on or under it.
5.5.
LOWERING
5.5.1.
Check beneath vehicle for any obstructions and remove axle stands.
5.5.2.
Slowly open release valve with handle and control the rate of descent by smoothly opening or closing the valve.
5.5.3.
Note: The release valve should not be closed abruptly (except in an emergency) since this shock loads the hydraulic system.
5.5.4.
After use jack should be stored with the piston and the manual pump socket both fully down.
