Installing the Air Filter/Mufler Cover
1. Place the air ilter/mufler cover over the back of the
carburettor and mufler.
NOTE: The choke lever must be in position B (Fig.
21) to install the air ilter/mufler cover.
2. Insert the four (4) screws into the holes in the air
ilter/mufler cover (Fig. 21) and tighten them. Use a
lat blade or T-20 Torx bit screwdriver. Do not over-
tighten. Do not use excessive force.

REPLACING THE SPARK PLUG

Use a type RDJ8J spark plug (or equivalent ). The cor-
rect air gap is 0.5 mm (0.020 in). Remove the plug after
every 50 hours of operation and check its condition.
1. Stop the engine and allow it to cool. Grasp the plug
wire irmly and pull the cap from the spark plug.
2. Remove any dirt from around the thread. Remove
the spark plug from the cylinder using a 5/8 in. spark
plug wrench and turning it counterclockwise.
3. Replace cracked, fouled or dirty spark plugs. Set the
air gap at 0.5 mm (0.020 in) using a feeler gauge
(Fig. 26).
4. Install a correctly gapped spark plug in the cylinder
head . Tighten the spark plug using a 5/8 in. spark
plug wrench and turning it clockwise until snug. Do
not over-tighten.
If using a torque wrench, torque to 12.3-13.5 Nm
(110-120 in.lb).

CLEANING AND STORAGE

CLEANING THE UNIT
Use a small brush to clean off the outside of the unit
and to keep the air vents free of obstructions.
CLEANING THE VACUUM BAG
1. Empty the bag after each use to avoid deterioration
and obstructions of the air low, which will reduce
the performance of the vacuum.
2. Wearing eye protection and a dust mask, clean the
bag as needed. Turn the bag inside out after empty-
ing and vigorously shake out dust and debris.
3. Wash the bag once a year or more often if needed.
Proceed as follows:
a. Remove the vacuum bag.
b. Turn the bag inside out.
c. Hang up.
d. Hose down thoroughly.
e. Hang to dry.
f. Turn bag right-side out and reinstall.
STORAGE
• Allow the engine to cool before storing.
• Store the unit in a locked-up place to prevent unau-
thorized use or damage.
• Store the unit in a dry, well ventilated area.
• Store the unit out of the reach of children.

LONG-TERM STORAGE

If the unit will be stored for an extended period of time:
1. Drain all petrol from the petrol tank into an appro-
priate container. Do not use petrol that has been
stored for more than 60 days. Dispose of the old
petrol in accordance to the respectively applicable
local regulations.
2. Start the engine and allow it to run until it stalls. This
ensures that all petrol has been drained from the
carburettor by using it up.
3. Allow the engine to cool. Remove the spark plug
and put 1 oz. (30 ml) of high-quality engine oil into
the cylinder. Pull the starter rope slowly to distribute
the oil. Reinstall the spark plug.
NOTE: Remove the spark plug and drain all of the
oil from the cylinder before attempting to start the
blower/vacuum after storage.
4. Thoroughly clean the unit and inspect for any loose
or damaged parts. Repair or replace damaged parts
and tighten loose screws, nuts or bolts. The unit is
ready for storage.
TRANSPORTING
• Allow the engine to cool before transporting.
• Secure the unit while transporting.
• Drain the petrol tank before transporting.
• Tighten petrol cap before transporting.
Waste disposal and environmental pro-
tection
Never pour remainders of chain lubricant or 2-stroke
fuel mixture in the drain or sewerage system or soil, but
dispose of it in a proper, environmentally friendly way,
e.g., at a special collecting point or dump.
