Section 4: Operation

7. Push the Primer Button (O, Figure 4-2)

three times (cover hole in center of

bulb when pushing).

8. To start engine with recoil starter:

a. Before pulling recoil starter (N,

Figure 4-2), be sure there are no

obstacles behind you.

b. Pull recoil starter handle rapidly to

overcome engine compression, pre-

vent kick-back and start engine.

Maintain control of rope so it slowly

returns into the starter mechanism.

Repeat pulling until engine starts. If

engine fails to start, repeat starting

instructions beginning with Step 3.

c. Let engine warm up. Rotate Choke

Knob (M, Figure 4-2) toward RUN

setting a little at a time over several

seconds in warm weather, or min-

utes in cold weather. Let engine run

smoothly before each change.

8. To start engine with electric starter:

WARNING

TO PREVENT ELECTRIC SHOCK:

•Do not use the 120VAC electric starter in the rain.

•Do not stand in water or on damp sur- faces when using the electric starter or when connecting power cord.

•Connect the power cord only to a prop- erly grounded, 120VAC wall outlet.

•Review electric start safety messages in the Engine Owner’s Manual and in Section 1 of this Manual.

a.Plug power cord supplied with unit into the electric start switch box (R, Figure 4-2) on the engine.

b.Plug the other end of the power cord into a properly grounded, 3- pronged 120VAC wall outlet.

IMPORTANT: To prolong starter life, use short starting cycles (five seconds maxi- mum, then wait one minute).

c. Push the starter button (P, Figure 4-2) on the switch box. When the engine starts, release the button.

Disconnect power cord from wall outlet and then from engine. (Store power cord in a secure place, safely out of the reach of children.) If en- gine fails to start, repeat starting in- structions beginning with Step 3.

NOTE: The starter is thermally pro- tected. If overheated from continu- ous use, it will stop automatically and can be restarted only when it has cooled to a safe temperature (a wait of approximately 5-10 minutes is required).

d. Let engine warm up. Rotate Choke Knob (M, Figure 4-2) toward RUN setting a little at a time over several seconds in warm weather, or min- utes in cold weather. Let engine run smoothly before each change. Operate engine with choke in RUN.

e. Allow unit to adjust to outside tem- perature before clearing snow.

STOPPING

Emergency stopping

1.Release both control levers (F and G, Figure 4-3).

2.Move the Throttle Lever (L, Figure 4-2) to the STOP position or pull the engine Stop Switch key (K, Figure 4-2) out.

WARNING

Do not attempt to stop engine by moving Choke Control to CHOKE. Backfire, fire or engine damage could occur.

Normal (non-emergency) stopping

1.Release both control levers (F and G, Figure 4-3). Wait for the unit to come to a complete stop.

2.Move the Throttle Lever (L, Figure 4-2) into the SLOW “ ” position. Allow the engine to idle for several minutes to melt any snow on the engine. Then move throttle to STOP position.

3.Pull engine Stop Switch key (K, Figure 4-2) out. To prevent unauthorized use of unit, remove key and store it in a safe place.

4.Rotate Fuel Shut-Off Valve (J, Figure 4-2) 1/4 turn clockwise to OFF (closed) position.

5.Disconnect the spark plug wire from the spark plug.

6.To help prevent possible freeze-up of controls:

a.Wipe all snow and moisture from vicinity of controls.

b.Move Throttle Lever back and forth several times and leave in STOP position.

c.Rotate Choke Knob several times

and leave in CHOKE position. 13
