Cleaning
External cleaning
•
Clean the machine daily by rinsing it with clean water after
the work is finished.
Cooling air intake
•
Clean the cooling air intake when needed.
NOTICE! A dirty or blocked air intake results in the machine
overheating which causes damage to the piston and
cylinder.
Spark plug
•
If the machine is low on power, difficult to start or runs
poorly at idle speed: always check the spark plug first
before taking other steps.
•
Ensure that the spark plug cap and ignition lead are
undamaged to avoid the risk of electric shock.
•
If the spark plug is dirty, clean it and at the same time
check that the electrode gap is 0.5 mm. Replace if
necessary.
NOTICE! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/
cylinder.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difficulties.
•
An incorrect fuel mixture (too much or incorrect type of
oil).
•
A dirty air filter.
Functional inspection
General inspection
•
Check that nuts and screws are tight.
MAINTENANCE
Drive belt
Check the tension of the drive belt
•
For correct tensioning of the drive belt, the square nut
should be positioned opposite the marking on the belt
cover.
Tensioning the drive belt
•
The tension of a new drive belt must be readjusted after
one or two tanks of fuel have been used.
•
When the machine is equipped with a friction retarder, a
scraping sound can be heard from the bearing housing
when the blade is turned by hand. This is quite normal.
Please contact Discount-equipment if you have any
questions.
•
The drive belt is enclosed and well protected from dust
and dirt.
•
When the drive belt is to be tensioned, release the bolts
holding the cutting arm.
•
Screw the adjuster screw so that the square headed nut
comes opposite the marking on the cover. This
automatically ensures that the belt has the correct
tension.
•
Tighten both of the screws holding the cutting head using
a T-wrench.
