•ATTACH OPERATING TUBE

NOTE: keep the throttle cable as straight as possible when connecting the blower tubes.

1.Place the unit on flat surface during assembly. Insure screw mechanism of clamp is positioned away from operator.

2.Put the hose clamp (C) on the flex tube(B) and the operating tube before connecting them together.

3.Turn the throttle linkage mark (D) so it aligns with the throttle handle (F) (Fig.3). Insert the operating tube

(E) into the flex tube (B) (Fig. 3) and then tighten securely with a hose clamp (G) (Fig. 4).

4.Attach throttle linkage clips to both ends of the flex tube to secure the throttle cable. (Fig. 6)

•ADJUST BACK PACK AND HARNESS AND CONTROL HANDLE

1.Place blower on your back by slipping arms through the shoulder straps as if you were putting on a jacket (Fig. 8).

2.Once adjustments have been made, to

the straps for user comfort, remove the

blower from your back and place on level ground in an upright position.

3.Adjust backpack harness and control handle.

FUEL AND LUBRICATION

•FUEL

Use regular grade unleaded petrol mixed with 40:1 custom 2-cycle engine oil for best results. Use mixing ratios in Section FUEL MIXING TABLE.

WARNING: Never use straight petrol in your unit. This will cause permanent engine damage and void the manufacturer’s warranty for that product. Never use a fuel mixture that has been stored for over

WARNING: If 2-cycle lubricant other than Custom Lubricant is to be used, it must be a premi- um grade oil for 2-cycle air cooled engines mixed at a 40:1 ratio. Do not use any 2-cycle oil product with a recommended mixing ratio of 100:1. If insufficient lubrication is the cause of engine damage, it voids the manufacturer’s engine warranty.

•MIXING FUEL

Add oil to an approved fuel container followed by the petrol to allow incoming petrol to mix with oil. Shake container to ensure thorough mix.

WARNING: Lack of lubrication voids engine warranty. Petrol and oil must be mixed at 40:1.

•ATTACH INTERMEDIATE TUBE AND

CONCENRATOR NOZZLE

Connect the intermediate tube (H) and concentrator nozzle (I) or 56mm nozzle (J) (you can only use one nozzle at a time). Push the tubes together and turn clockwise until they lock together (Fig. 7). Use concentrator nozzle when you need more airflow in tight places: flower beds, under decks, etc.
