OPERATION
OPERATION
Figure 3
3. If the engine is cold, close choke (b1) on the carburetor.
NOTE:
Occasionally, warm engines will need to be choked.
4. With throttle in idle position (c3), pull the starter rope (a) until the engine starts.
5. On engines equipped with the low oil shutoff switch, see section Low oil Shutoff Switch for additional information.
NOTE:
First time use, engines recently serviced, run out of fuel or not used for long periods of time may need the rope
to be pulled more times to move fuel to the carburetor.
6. Open choke (b2) on the carburetor as the engine warms up.
NOTE:
A cold engine should be allowed to warm up at the idle position (c2) for approximately one (1) minute. Failure to
open the choke after the engine attempts to start may cause flooding.
CAUTION:
Always open choke (b2) with throttle in idle position (c3). Opening choke with throttle not in idle position
(c3) may result in rammer motion.
See Figure 2
1. Place throttle in the idle position (c3).
2. Turn engine switch to“OFF” (d).
3. Close fuel valve (e).
• If the warning light flashes quickly once, this indicates the engine oil level is acceptable.
• If the warning light flashes slowly, the engine will start but shut off after 10-12 seconds, this indicates that the engine
oil level is low. Add oil to the engine. See Technical Data for oil quantity and type.
• If the warning light stays on continuously, the engine will start and continue to run but the low oil shutoff switch is not
functioning properly. Check the switch for proper wire connections. If the light continues to stay on, replace the switch.
• If the warning light does not flash quickly once, and the engine starts and continues to run, the low oil shutoff switch
is not functioning properly. Check the switch for proper wire connections and grounding. If the light still does not flash
when starting the machine, replace the switch.
The low oil shutoff switch is designed to prevent engine damage caused by an low engine oil level.
When starting the machine:
See Figure 3
Keep vibratory rammer clean and dry. Avoid no-load strokes. Never
allow the rammer to run full throttle when forcing away material or
when lifting the equipment.
For optimal control, performance, and minimal hand/arm vibration,
grasp the handle as shown. Hand/arm vibration (HAV) has been
optimized for this positioning. Reported HAV levels are measured at
position A just in front of the hand position shown in conformance
with EN 1033 and ISO 5349.
