Operating Instructions
To raise hoist
Note: read the safety precautions on page 2 before using.
1. Check the hoist arms are clear of the vehicle access area
before driving on.
2. Park the vehicle centrally on the hoist.
3. Position the lifting pads under the vehicle at the pick-up
points approved by the vehicle manufacturer. Adjust the lifting
pad heights to ensure they all lift evenly. Check the lifting arms
and pads will clear the vehicle body, exhaust pipes, etc.
4. Check all personnel are clear of the hoist and vehicle, turn
the isolating switch to the “up” position and raise the vehicle
approximately 500mm, allowing the hoist to take the full weight
of the vehicle. Watch the vehicle while raising.
5. Check that the lifting pads are correctly positioned at the
pick-up points on the vehicle and evenly loaded. Lower the hoist
and re-adjust if necessary. Check the lifting arms are locked into
position. Shake the vehicle to check it is stable.
6. Raise the hoist to the desired height for working on the
vehicle. Watch the vehicle while raising to make sure it will not
collide with anything and stays level and stable.
7. Before commencing work on the vehicle, check the lifting
pads are correctly positioned at the pick-up points and the
lifting arms are locked in position. Lower the hoist and re-adjust
if necessary.
Turn the isolating switch to the horizontal “off” position. This will
stop the hoist and make it safe if there is an electrical fault.
To lower hoist
1. Check the floor area beneath the hoist and vehicle is clear of
people, parts, tools and equipment.
2. Lower the hoist fully. Watch the vehicle while lowering to
make sure it will not collide with anything and stays level and
stable.
3. Move the lifting arms clear of the vehicle before driving the
vehicle off the hoist.
Routine Maintenance
Warning: Always maintain the hoist to keep it safe and reliable.
Daily
1. Lower the hoist to floor level. Check that a gap exists between
lift and safety nuts on both columns.
2. Clean the lifting pads to remove any oil or grease. Inspect
them for any deep cuts or other damage. Replace if damaged.
Monthly
1. Raise the hoist 500 mm. Put a dipstick through the hole in the
column blind down into the oil reservoir. Remove the dipstick
and check the oil level. The oil reservoirs must be kept half-full
(halfway to the bottom of the hole in the blind). Do not overfill.
Recommended oils:
Ampol AP80W/90
Caltex Thurban EP80W/90
Esso GX 80W/90
Shell Spirax 80W/90
BP GRXP 15
Castrol HYPOY C80W/90
Mobil Mobilube HD90
Valvoline 18MD 80WD/90
Do not use any other oil or any oil additives.
2. Check the vee belt tension. Individual belt deflection must
be less than 10 mm when pressed firmly in mid-span with your
thumb.
Every 3 months
1. Measure the gap between the lift and safety nuts in each
column. If the gap has decreased from the initial setting by 1.5
mm or more, then arrange for the replacement of the lift nut.
2. Remove the base frame ramp and oil the chain. Check and re-
tension as per installation instructions Step 13. if required. If out
of adjustment, shorten the chain on link (remove a maximum of
three links).
Note: use 2 people to lift the ramp.
3. Test the arm locks are moving freely and locking on securely.
4. Grease the top bearings in the columns.
5. Check the operation of the top and bottom limit switches.
6. Lightly oil the arm pivot pins and lifting pad adjusting screws
and other bearing surfaces to allow free movement.
7. Check the footguards are fitted and in good condition.
8. Check that all visible bolts and nuts are tight including the
hold down bolts in the floor.
Major Service
Note: use lifting equipment or extra people to lift or handle the
heavy parts.
To Dismantle Column
1. (a) Raise the hoist approximately 1 metre.
(b) Switch off the power at the mains isolating switch, adjacent
to the hoist.
(c) Disconnect cables at the isolating switch (electrician
required) if working on the drive column.
(d) Remove the blind from the column.
(e) Use a suction pump to remove oil from the reservoir.
2. (a) Remove ramp from the base frame and remove arms from
the carriage.
(b) Release chain tension by moving chain guides.
(c) Undo two screws on chain limit switch and remove the
bottom limit switch cover (drive column).
(d) Remove bolts securing base plate of column to base frame.
(e) Slide the column in towards the centre of the base frame
and remove the chain from the sprocket under the column base
plate.
3. (a) Tilt the column back and lower gently to rest on a suitable
support approx. 150 mm high on the floor.
4. (a) At the base of the column, remove the nyloc nut and
withdraw the sprocket from the screw. Remove the key.
(b) Undo the two cap screws that hold the bottom bearing
housing and reservoir in place.
5. (a) At the top of the column, remove the drive cover and vee
belts (drive column only).
(b) Remove the four nuts securing the top plate to the column
(the large pulley may be left in place). Withdraw the top plate
and screw assembly a distance of approximately 500 mm and
place a support under the screw inside the top of the column.
6. (a) Slide the bottom bearing housing off the bottom of the
screw.
(b) Unscrew the lift screw out of the lift and safety nuts in the
carriage. Take care not to damage the screw thread or sealing
surfaces.
(c) Remove the two nuts and the nylon load ring from the
carriage.
(d) Roll the carriage up and out of the top of the column.
