Operating Instructions
To raise hoist
Note: read the safety precautions on page 3 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, switch on isolator, wait until the light comes
on then press the raise button and raise the vehicle
approximately 500 mm, 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 and will protect the hoist electrics from
high voltage spikes.
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 500mm. 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
Esso GX 80W/90
BP GRXP 15
Mobil Mobilube HD90
Caltex Thurban EP80W/90
Shell Spirax 80W/90
Castrol HYPOY C80W/90
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. Test the operation of the overhead trip bar by lifting
up the trip bar at mid-span while driving the hoist up.
It must stop.
3. Test the arm locks are moving freely and locking on
securely.
4. Grease the top bearings in the columns.
5. Check the brake shoes and the inside of the screw
pulleys are clean and free of grease or dirt.
6. Check the operation of the top and bottom limit
switches.
7. Lightly oil the arm pivot pins and lifting pad adjusting
screws and other bearing surfaces to allow free
movement.
8. Check the footguards are fitted and in good
condition.
9. Check that all visible bolts and nuts are tight
including the hold down bolts in the floor.
10.Check there is a 0.5 to 1.0mm gap between the
proximity switches and the screw pulleys (when the
hoist is not loaded).
Major Service
Note: Use lifting equipment or extra people to lift and
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) At the top of the column, remove the drive cover
and vee belts.
(d) Remove the blind from the column.
