7. Cleaning, maintenance, storage and
ordering of spare parts
7.1 Cleaning
• Keep all safety devices, air vents and the motor
housing free of dirt and dust as far as possible. Wipe
the equipment with a clean cloth or blow it with
compressed air at low pressure.
• We recommend that you clean the device
immediately each time you have finished using it.
• Clean the equipment regularly with a moist cloth
and some soft soap. Do not use cleaning agents
or solvents; these could attack the plastic parts of
the equipment. Ensure that no water can seep into
the device.
7.2 Maintenance
Always switch off the hedge trimmer and remove the spark
plug boot (Fig. 13) before carrying out any maintenance
work.
1. The cutter blades are high quality, made of tempered
steel and in normal use there is no need to sharpen
the blades. If you accidentally strike a wire, stone,
glass or other hard object, this may cause a notch
in the blade. There is no need to remove the notch
as long as it does not adversely affect the movement
of the cutting edges. If it does adversely affect this
movement, switch off the machine and use a fine file
or a fine grinding stone to remove the notch. Ensure
that the blade’s cutting edge is always well oiled
(see Fig. 8).
2. If you drop the hedge trimmer, check whether it has
suffered any damage. If it is damaged contact the
Argos general enquiries 0845 640 3030.
3. Only clean the machine after it has been switched off.
Use only mild soap and a damp cloth to clean it. Never
allow fluid to get into the machine. Do not use caustic
cleaning products.
7.2.1 Maintenance of the air filter (Fig. 9-11)
Soiled air filters reduce the engine output by supplying
too little air to the carburetor.
Regular checks are therefore essential. The air filter
should be checked after every 25 hours of use and
cleaned if necessary. If the air contains a lot of dust,
the air filter should be checked more frequently.
1. Remove the air filter cover (Fig. 9-10)
2. Remove the filter element (Fig. 11)
3. Clean the filter element by tapping it or blowing it.
4. Assemble in reverse order.
Please note: Never clean the air filter with petrol or
inflammable solvents. Clean the air filter with
compressed air or by tapping it.
7.2.2 Maintenance of the spark plug (Fig. 12-14)
Spark plug gap = 0.025 inch (0.635 mm). Tighten the
spark plug with a torque of 12-15 Nm.
Check the spark plug for dirt and grime after 10 hours of
operation and if necessary clean it with a copper wire
brush. Thereafter service the spark plug after every 50
hours of operation.
1. Pull off the spark plug boot (Fig. 13) by twisting.
2. Remove the spark plug (Fig. 14) with the supplied
spark plug wrench.
3. Assemble in reverse order.
7.2.3 Maintenance of the gearbox (Fig. 15)
The gearbox must be lubricated every year before the
start of the season at the lubrication nipple (Fig. 15/Item
A). Place a conventional grease gun on the nipple and
press approx. 3 strokes of conventional machine grease
into the gearbox. If you use the trimmer frequently, grease
the gearbox more often.
7.2.4 Carburetor settings
Important.
Settings on the carburetor may only be made
by authorized customer service personnel. The air filter
cover must be removed before any work on the
carburetor, as shown in Figures 9 – 10.
Setting the throttle cable:
If the maximum speed of the machine falls over time and
you have ruled our all the other causes listed in section 9
Troubleshooting, it may be necessary to adjust the
throttle cable.
First of all check whether the carburetor opens fully when
the throttle handle is pressed fully. This is the case if the
carburetor slide (Fig. 16/Item 1) rests against the stop
(Fig. 16/Item 2) when the throttle is fully open. Figure 16
shows the correct setting. If the carburetor slide does not
touch the stop, it must be adjusted.
The following work is required to adjust the throttle cable:
•
Undo the lock nut (Fig. 16/Item 3) a few turns.
• Undo the adjusting screw (Fig. 16/Item 4) until the
carburetor slide rests against the stop when the
throttle is fully open, as shown in Figure 16.
• Retighten the lock nut.
Setting the idling speed:
Important.
Set the idling speed when the machine is warm.
If the engine stalls when the throttle is not pressed and
you have ruled out all the other causes listed in section 9
Troubleshooting, the idling speed must be adjusted. To do
this turn the idling speed screw (Fig. 16/Item 5) clockwise
until the machine runs smoothly at idling speed.
If the idling speed is so fast that the cutting blades do not
reach a standstill, the idling speed must be reduced by
turning the idling speed screw (Fig. 16/Item 5)
counterclockwise until the cutting blades stop.
