Air filter
Accumulated dust in the air filter will reduce engine
efficiency, increase fuel consumption and allow abrasive
particles to pass into the engine. Remove the air filter as
often as necessary to maintain a clean condition.
IMPORTANT. The air filter should
be checked approximately
every 10 hours of use, or more
frequently in dusty areas.
1. Remove the air filter
cover retaining screw (15),
and remove the cover and
filter element.
2. Inspect the element. If
the element is distorted or
damaged, replace it with a
new one.
3. Wash the filter in detergent
and water. Rinse the filter
thoroughly. Squeeze out
excess water. Allow it to dry
completely before reinstalling.
4. Install the element and
cover and then tighten the
retaining screw.
Useful tips
• Light surface dust can
readily be removed by
tapping the filter.
• Heavy deposits should be washed out in suitable detergent.
• Squeeze out the remaining water and allow the filter to
completely dry.
• Add a drop of thin oil to the filter and replace it.
Servicing
• It is recommended once you first use your petrol blower
have it serviced after 15 hours of use by an authorised
service centre.
• From thereafter, service the petrol blower every 2 years.
Storage and maintenance after use
• When you finish working, clean the petrol blower completely.
• Inspect the entire blower and tubes for damage,
including loose or missing components, and repair
anything necessary.
• Store the petrol blower away from direct sunlight.
• Do not store in a nylon bag as this can encourage the
formation of mould.
• Use a small brush to clean off the outside of the unit and
keep the air vents free from obstructions. Do not use
water or a hose to clean the unit.
Whenever the machine is not used for a long period of time,
proceed as follows:
• Give the petrol blower an overall cleaning and a
thorough check.
• Empty the fuel tank completely, then clean the
carburetor and lines by running the blower until it stops
from lack of fuel.
• Protect all metal engine parts from corrosion by coating
them with oil.
• Remove the spark plug, put several drops of oil into the
cylinder through the spark plug hole and then pull the
recoil starter 2 to 3 times in order to distribute the oil
evenly. Replace the spark plug and spark plug cover.
• Clean the air filter as described in the air filter section.
