This vehicle hoist is not designed to be used for
steam cleaning nor to be installed in the open
exposed to the elements. Vehicle hoists installed
under such conditions are not covered by our

When installed in tropical environments it is
advisable to raise the hoist to full height when not in
use overnight or on weekends, to minimise
condensation forming inside the cylinder which may
lead to corrosion of cylinder bore.

INTRODUCTION
Here is the MOLNAR CLEAR FLOOR HOIST, a space saving wheel-free hoist
and its many advantages.
It has been purposely designed for space saving and to give versatility and
profitability to the largest garage and smallest service station. Safe, strong,
simply built to give years of trouble-free service. The MOLNAR CLEAR
FLOOR HOIST embodies many features that make it the most up-to-date
equipment for quicker and more profitable service.
SAFE AND EFFICIENT OPERATION
Molnar Hoists use an electro hydraulic system which gives years of trouble
free service. Raising and lowering of vehicle is controlled by hydraulics, plus
built-in mechanical safety against any failure together with “deadman”
controls.
INSTALLATION
The MOLNAR CLEAR FLOOR HOIST PREMIUM is fast and simple to install
only 16 expanding sleeve anchors are needed for a suitable floor. No costly
excavation. It is also ideal for upper floor level where excavation is not
possible. The hoist is surface mounted a feature which means lower overall
cost. Compared with similar-priced hoists the MOLNAR CLEAR
FLOOR HOIST can be quickly, easily and economically re-sited.

INTRODUCTION
FOR SPEEDIER SERVICE
With the MOLNAR CLEAR FLOOR HOIST maximum accessibility is assured.
No cumbersome beams or cross-sections impede the operator in any way,
giving the hoist unlimited advantages, when used for unit replacement. With
this lifting method the suspension springs are relaxed, facilitating lubrication
and repair work. Wheel service, brake adjustment, washing underbody
spraying or sealing or any underbody repairs can be speedily carried out.
EASY TO OPERATE
The MOLNAR CLEAR FLOOR HOIST is operated with the greatest of ease.
The telescopic adjustable arms and contact pads are easily placed in position
by one man. The operator has full confidence due to the mounting of the arms
and the area of the chassis which can be contacted. The vehicle is
immediately wheel-free and stable at any height.

FLOOR REQUIREMENTS FOR MODEL 2P4T
These notes are for your guidance prior to installation.
1. It is the users responsibility to provide a satisfactory site area.
2. The floor should be a single reinforced concrete slab.
Min concrete thickness = 100mm
Min plan dimensions of 4600mm x 1800mm
Prepared base 100mm thickness of quarry rubble compacted to
95%
SL81 reinforcement mesh
Min thickness of concrete above mesh = 65mm
25Mpa concrete
3. For correct installation of the Clear Floor Hoist the floor must be flat and
level. A level tolerance between posts of 10mm is allowable. Check with
straight edge and spirit level. (Ref. Fig. 1).
4. Recommended anchor bolts are expansion sleeve type anchors 20mm
diameter with a minimum length of 82mm. Use the manufacturers
recommended installation procedures.
NOTE: Some authorities do not approve expanding type anchorage
devices.
5. If there is any doubt about the quality of the floor, a replacement slab
should be installed. Use a qualified person to design the replacement
slab.
6. No liability for any damages will be accepted should you install the hoist
on an unsuitable floor.

OPERATING INSTRUCTIONS
1. Position vehicle central to the hoist
posts.
2. Place the four pads under the vehicle
at vehicle jack points.
3. Raise the vehicle with the hoist until
the wheels have just left the ground
and check that the load is balanced,
stable and the pads are located
correctly. If not correct lower vehicle to
the ground and reposition vehicle and
pads as necessary and check again.
4. Press starter button and raise vehicle
to required height. Do not go under
vehicle until load rests on safety.
5. When vehicle reaches maximum
height limit switch will come into
operation and stop hoist. When hoist
has stopped, pull release lever until
load rests on safety.
6. Before lifting, the safety lever should
be in the “ON” position. During lifting
with the automatic safety “ON” a
clicking sound should be noticeable,
this indicates the safety mechanism
operating. If this sound is not heard,
immediately cease using the hoist and
call an authorised service agent.
7. When the required height is reached,
stop the hoist, ensure the safety lever
is in the “ON” position and then lower
load until safety mechanism pawl
comes to rest on a ratchet tooth and
supports the load together with the
wire ropes.
8. To lower the hoist, first raise it
approximately 20mm, push the safety
lever to the “OFF” position and pull the
release lever down.

OPERATING INSTRUCTIONS
9. If the car is to be worked on at an
intermediate level, load must be once
again secured as detailed in step 7.
10. WARNING: Do not go under the
vehicle under any circumstances while
the vehicle is being raised or lowered.

NOTE: Refer to trouble shooting chart, page 11, for fault remedies.
YEARLY
Service and safety inspection on the hoist must be performed by a competent
person. This inspection must be recorded. If the 12 monthly service and safety
inspection is not performed, the warranty is null and void.
NOTE: Yearly service must include removal of rollers and pulleys to inspect,
clean and lubricate bushes and pins.
2 YEARLY
Hydraulic oil and filter should be replaced. Fill Oil Tank to Oil Level Line with
Shell Tellus T46 oil, Mobil DTE25 oil, Castrol Hyspin AWH46 oil, BP Bartran
HV46 oil or equivalent.
