PREPARING THE MACHINE
BEFORE STARTING TO USE THE MACHINE
Delivery of the machine, explanation relating to the safety regulations,
operation, maintenance as well as the first start-up are usually
performed by an authorized COMAC operator. If this is not done then
the user is responsible for training those who shall use the machine
concerning the operating and safety regulations illustrated in the
following pages of this manual.
MOVING THE PACKAGED MACHINE
The machine is contained in specific packing with a platform so that it
can be moved by a fork-lift. The pallet contains both the packing with
the base and that with the handlebar. More than two packings cannot
be stacked.
Total weight is 50 kg.
Packing dimensions are:
A: 65 mm
B: 80 mm
C: 120 mm
UNPACKING THE MACHINE
1. Open the top part of the external packing
2. Lift the base of the machine up and out
3. Remove the handlebar from its packing
4. Mount the handlebar on the base (see the paragraph:
"INSTALLING THE HANDLEBAR")
5. Keep the packing in storage for any future shipping
requirements.

7
PREPARING THE MACHINE
INSTALLING THE HANDLEBAR
Insert the handlebar in its vertical position, placing the support in the
four holes on the base. Insert the four M8 screws.
Tighten the screws one at a time, holding the self-locking nuts below
the base in their seats.
Connect the gas spring to the support by pressing it in by hand.
Connect the power cable to the motor.
INSTALLING THE PAD
WARNING! Check that the power plug is
disconnected from power mains and wear suitable
protective gloves before you proceed to install the
pad.
Use the handlebar to slope the machine back until it rests on the floor
(handlebar horizontal, machine vertical). Remove the clip from the
motor hub and screw on the drive disk. Mount the pad on the disk,
supporting it with one hand and tightening fastening ring (2) with the
other

Use the handlebar to bring the machine back up into its vertical
position.
The machine must be perfectly horizontal and positioned on the
vertical of the disk.
Connect the power plug into the power mains. Move the handlebar
horizontally until you achieve proper rotation stability. Then release
the levers to turn the machine off.

PREPARING THE MACHINE
Pull positioning lever (A) to lower the handlebar until the user's arms
are at a comfortable angle. Push lock lever (B) down with your thumb
and then actuate the motor using the two levers (C).
The lock lever must be released every time the machine is started up.
For safety reasons the motor cannot be activated when the handlebar
is in its vertical position.
WARNING! Use only special high speed disks as
specified in the last chapter of this manual, "Polishing
pads selection and use". Order these disks from
COMAC or from one of their authorized dealers.

Use only disks provided with the appliance or disks specified in this operating and maintenance manual. Use of
other disks may jeopardize safety.
The machine must only be used by authorized persons who have been properly trained regarding machine operation
and are aware of these safety regulations.
The power cable outlet must have a proper grounding.
Avoid touching or running over the power cable when the disk is operating. Avoid damaging it by crushing, bending
or stressing it.
Whenever you encounter damage in the power supply cable you must immediately stop the machine if it is at work,
pull the plug out from the power supply mains and replace the cable with a new one from a COMAC service center.

OPERATION
GETTING SET TO OPERATE THE MACHINE
Pull positioning lever (A) to lower the handlebar until the user's arms are at a
comfortable angle. Push lock lever (B) down with your thumb and then
actuate the motor using the two levers (C). The lock lever must be released
every time the machine is started up. For safety purposes the motor cannot
be activated while the handlebar is in its vertical position.
OPERATING THE MACHINE
The first time you use the machine you must become familiar with the
movements to impart on the handlebar in order to be sufficiently sure about
the direction the machine will move. Do not use the machine near persons or
obstacles until you have become familiar with it.
Work by performing back and forth movements and if possible going
backwards so that the operator is always standing on a floor that has not yet
been polished.
Keep the power supply cable behind the operator. Be careful not to work with
the machine near this cable in order not to damage it.
Do not work too long on the same zone in order to avoid damage to the
floor.

11
AFTER WORK IS TERMINATED
REMOVING THE PAD
To remove the pad bring the handlebar up to vertical by pulling on the
positioning lever. Then tilt the machine back by resting it on the wheels. Use
the specific handle to unscrew the ring that clamps the pad in place and
remove the pad. Now unscrew the fastening screw located in the center of
the pad.
The machine must never remain resting on the pad.
In fact the weight of the machine could permanently deform the pad or the
disk and create vibrations and oscillations when working.
WARNING! Pull the plug out of the power supply outlet
before performing any type of maintenance and at the end of
the work cycle.
WARNING! Abrasive disks can be installed manually only
after pulling the power supply plug out from the power outlet
and only when wearing suitable protective gloves.

12
DAILY MAINTENANCE
CLEANING
Before you put the machine away:
- examine the power cable and check it has not been damaged;
- clean the machine with a damp cloth.
- Periodically check the condition of the pad and replace as
necessary.

13
CHECKING OPERATION
THE MACHINE DOES NOT CLEAN WELL, VIBRATES OR OSCILLATES
Check the condition of the abrasive pad.
If the machine has been resting too long on the abrasive pad the pad may
have been permanently deformed. This will cause the machine to vibrate. If
the pad is ruined or worn then it must be replaced with a new pad.
To replace the pad consult the paragraphs: "REMOVING THE PAD" and
"INSTALLING THE PAD".
THE MACHINE STOPS WHEN IT IS AT WORK
The machine has an amperometric safety switch located behind the handlebar
that cuts off power to the brush motor whenever a predetermined load is
exceeded. To give current back to the motor you must press the push-button.
If the switch continues to cut off power then you must call your nearest
COMAC service center.
MOTOR SIGNAL LAMP ON
The machine has a device that checks the state of wear of the motor brushes.
The motor brushes must be replaced when the red signal lamp turns on (see
the figure). This procedure must be done by qualified personnel from a
COMAC service center.
WARNING! Ask for service from a COMAC service center
whenever you encounter any other malfunction.
