For the implementation procedure, please see the used dowel manual.
Caution with all handling operations. Strictly observe the elementary safety rules that relate to
the used elevation means.
Special installation conditions
The R4 LPW lift platform scale must be installed on a perfectly flat surface. The adjustment of
horizontality must be done in factory.

Installation 2
Introduction
The receptor and/or ramps can be handled using the handling device and adapted slings or by several people.
The front handles (
1
) and the rear openings (
2
) are used as lifting points.
Caution with injury hazards when handling the platform scale and/or access ramps.
Setting up the platform scale
Platform scale alone
•
Setting the platform scale on the ground at the wished location. As much as possible, plan to have sufficient
space around the receptor so as to ease cleaning operations.
•
On each side of the platform scale, drill the 3 holes* to fix the whole set in the ground through the orifices
specially designed for this (
3
) on the lift plates (
4
).
•
Fasten the 6 screw/washer fixing sets.
•
Unscrew the 2 screw/washer sets (
5
) of each of the 4 transport brackets (
6
) and withdraw the brackets.
* Fastenings not supplied. SPIT dowels with M16 x 120 screws and washers recommended.

Ramp
•
Position both plates (
1
) aligned with the two lift plates (

) on the
plates (
1
).
•
For each plate, fasten the 2 fixing screw/washer sets.
•
Position the ramp (
1
) at the platform scale entry by matching the ramp sheet (
2
) with the two squares welded

Cleaning and maintenance 4
General recommendations
We differ common daily cleaning and the complete cleaning that needs to be performed once a week. Th type
of cleaning depends on the use: dry cleaning in case of powdery products and with water in other cases.
The temperature of the water used during cleaning must not be over 60 °C.
Daily cleaning
•
With the platform scale horizontal, clean all the elements of the platform scale that are accessible, insisting
particularly on the areas that are harder to access, mainly the elements of the lifting parts.
When doing this cleaning, cross the jets and make sure to push the water outside.
•
Proceed to lifting the platform scale up (See "Lifiting", page 11).
•
Proceed to the same cleaning under the platform scale.
•
Put the platform scale back to horizontal (See "Putting back to horizontal", page 11).
Weekly cleaning
The principle of the weekly cleaning is identical to the daily one, apart from the two following differences.
Platform scale horizontal
When the platform scale is horizontal:
•
Make sure that the two blocking spanners (
1
) are well fastened.
•
Unfasten the 2 fixing screws (
2
) of each of the 4 blocking spanners (
3
) and remove them.
•
Proceed to the common cleaning of the upper part of the platform scale.
•
Remount the 4 blocking spanners.

Platform scale lifted up
When the scale is up:
•
Unscrew the 8 fixing screws (
1
) of each of the two lateral protection sheets (
2
). Be cautious with the
waterproof sealing (
4
).
•
Clean the totality of the underside of the platform scale, including the lateral compartments (
4
).
Do not use detergent so as not to damage the cylinders.
Leave the compartment insides to dry completely prior to remounting.
•
Once the cleaning over, remount the lateral protection sheets and proceed to the closing of the platform scale
(See "Lifting up", page 11).
Maintenance
•
In cases where a greasing of cylinders is necessary, use H1 quality grease.
