3.2 Danger while working with the machine
The 390 Surface Prep is designed to the highest technical standards.
Incorrect use can be dangerous!

Disturbances that could impair safety have to be eliminated at once.
3.3 Restriction of use
The 390 Surface Prep Machine is exclusively for wet cleaning and polishing of
resilient and textile floor coverings and for grinding pavement and leveling
compounds in dry environments. It should not be used for any other purpose. Sinclair
is not responsible for any damage or loss caused by incorrect use.
3.4 Genuine Spare Parts
Spare parts and accessories are manufactured uniquely for the 390 Surface Prep
Machine. It must be emphasized that parts obtained from unauthorized sources must
not be used.
Sinclair Equipment Company cannot be held responsible for the performance of
or any damage arising from the use of machines in which genuine spare parts have
not been used.
This is particularly important with mounting discs, disc and brushes.
4.0 Maintenance

5.0 Use
Getting started
The 390 Surface Prep is shipped in two separate boxes. Mount the handle with four
screws, safety washers and nuts to the machine (Pos. 16).
Connect the power cord of the handle with the machine.
Mount the handle with the cable entry (5) backwards (towards the user).
Otherwise the machine will not operate.

Assembly of mounting discs, pads and brushes
Lay the machine down on the handle. Thus the support of the discs is accessible. Put
the mounting disc on the actuation and lock it by turning counter-clockwise.
Assembly of the vacuum unit
Assemble the vacuum unit with two supports to the handle.
- insert lower connector into the plastic mounting
- lock the upper connector by shifting the upper plastic mounting down
The upper plastic mounting can be shifted by loosening the screws.
- Mount discs and brushes as described in item
- Connect the vacuum ring and the vacuum with the tubes
5
- Put the handle (2) in working position with the big, right lever (1). We
recommend positioning the handgrip in the height of the
user’s hip.
- Lift the handle slightly, to make sure the machine stands horizontally.
- Move the left or right safety lock (3) located onto the grip inwards.
- Switch on the machine with the respective lever (4).
After switching on the machine, the handle will move shortly to the right.
The direction in which the machine moves, is controlled by lifting or lowering the
grip. The more you lift or lower the grip, the faster the machine runs to the
corresponding direction.
-lifting the grip: machine runs to the right
-lowering the grip: Machine runs to the left
Lever (4) can only be actuated, if the handle is not in vertical position. This is a
safety feature! The user cannot control the machine with vertical handle.
If you feel unsafe or cannot control the machine just release lever (4). The machine
will stop at once. If you have carried out some training, you will be able to operate
the machine with one hand.
Always remove discs or brushes after work. Remove also the cleaning tank, if one
has been used. Always disconnect the power cord after work or when leaving the
machine.
Operation with vacuum cleaner
Note: the vacuum cleaner cannot – on technical grounds – remove the grinding dust
from under the discs. It will always remove the fine dust. To clean the floor, use an
industrial cylinder vacuum cleaner.
