Maintenance; Faults And Trouble Shooting; Service - Husqvarna PG280 Operator's Manual

Faults and trouble shooting

The machine does not start
• Check the power supply and the power cables to
make sure they are not damaged.
• Check that the emergency stop button is not pressed
by turning it clockwise.
• Check the overload lamp. If the overload lamp is on,
allow the motor to cool down for a few minutes until the
machine is automatically reset.
Machine is hard to hold onto
• Too few diamonds under the machine or the wrong
type of tool for the application (stiff adhesive or soft
floor coverings result in high stress to the machine
and the user if there are too few diamonds under the
machine). Usually also accompanied by high current
draw by motor.
Use the number of diamonds recommended by
Husqvarna to reduce the stress on the grinder and the
user.
Machine is jumping around
• Diamonds may not be fitted correctly or have different
heights. Check to ensure all diamonds are fitted
correctly and are the same height.
The machine stops after just a while
• The machine is overloaded and the overload
protection has been released. Reduce load. The
machine will reboot after about a minute when the
engine has cooled off.
NOTICE! The lower hole for a higher handlebar and
greater grinding pressure. The upper hole for a lower
handlebar and less grinding pressure.
• Ensure any extension cables are not under
dimensioned.
The machine stops during start-up
• The electric motor has overloaded and the overload
lamp is on. Give the machine one or two minutes to
reset and try again. When this does not help, contact
an authorised service workshop.

MAINTENANCE

• Ensure any extension cables are not under
dimensioned.
NOTICE! Good motor performance depends on proper
voltage. Extension cables that are too long and/or which
have a gage that is too small, reduce power to the motor
under load.
Maintenance
IMPORTANT! Inspection and/or maintenance should be
carried out with the motor switched off and the plug
disconnected.
Used correctly, the machine is an extremely low-
maintenance and reliable product.
Daily Maintenance
• Cleaning

Cleaning
Always pull out the plug from the outlet socket before
cleaning, maintenance or assembly.
Always clean all the equipment at the end of the working
day. Do not use a high pressure washer to clean the
machine.
In order for the machine to always be cooled sufficiently
the cooling air openings must be kept clear and clean.
Electrical Feed

Check that the cord and extension cord are intact and in
good condition.
Never use the machine if the cord is damaged, hand it in
to an authorized service workshop for repair.
