MAINTENANCE AND REPAIR INSTRUCTIONS

REPLACING THE SPARK PLUG

Use a Champion RDJ7Y spark plug (or equivalent). The correct air gap is 0.5 mm (0.020 in.). Remove the plug after every 25 hours of operation and check its condition.

1.Stop the engine and allow it to cool. Grasp the plug wire firmly and pull the cap from the spark plug.

2.Clean dirt from around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8 in. socket counterclockwise.

3.Replace cracked, fouled or dirty spark plug. 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 by turning the 5/8 in. socket clockwise until snug.

If using a torque wrench, torque to;

12.3-13.5 N•m (110-120 in.•lb.). Do not over tighten.

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 obstructing air flow, 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 initial emptying and vigorously shake out dust and debris.

3.Wash the bag once a year or more often if needed:

a.Remove the vacuum bag.

b.Turn 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 locked up to prevent unauthorized 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 time,

1.Drain all petrol from the petrol tank into a container. Do not use petrol that has been stored for more than 60 days. Dispose of the old petrol in accordance to 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.

3.Allow the engine to cool. Remove the spark plug and put 30 ml. (1 oz.) of high quality motor 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.
