Operation
Filling in the engine oil (Fig. B1)
Before starting up, you have to fill in 0.3 l of the brand-name oil HD SAE15-W40 up to “max” marking on the dip stick (not above
the marking). Plug in the dip stick in accordance, check the oil level.
Before scarifying, always be sure to check the oil level.
Filling in fuel (Fig. B2/B4)
No smoking, and no open flames!
Do not tank up with the engine running. Do not squirt fuel while the engine is warm. Use
lead-free regular petrol (not Super Plus). Avoid spilling petrol. Do not inhale the vapours.
Adjustment of working depth
Proceed only with motor switched off and tines at complete standstill. The unit is supplied with tines set at highest working posi-
tion. Adjust working depth to suit lawn condition.
•
Working lever should always be placed in „start” position (Fig. B3, a)
•
Turn hand wheel (Fig. B4) by 8–10 turns to the left (1 x turn = 1 mm working depth)
•
Scarifying test
- start motor
- move working lever s lowly forward (Fig. B3, b)
- Push unit slowly forward into the direction of working
- when hitting foreign object (stone, etc.) or motor stalls
•
Switch off motor immediately
- turn hand wheel by 2–3 turns to the right
- test scarifying action again
•
The working depth can be adjusted infinitively according to the condition of the ground and/or the wear of times.
Recommended working heights:
10
Maintenance
Before all maintenance and cleaning work, pull off the spark plug connector.
After each use, clean the scarifier with a hand brush (Fig. B7).
Do not by any means spray down with water. Store the scarifier in a dry room.
Always change the engine oil with the engine warm, and the tank empty.
Do so the first time after the first 20 hours of operation. Then every 100 hours of operation, or no later than the end of the mowing
season. When used under difficult or dusty conditions, do so more frequently. Open the oil filling connection piece, slowly tilt the scarifier
to the side and let the oil drain out. Dispose of the used oil according to local regulations. Note: Oil must not get into the ground.
Clean the spark plug
Dirty spark plugs reduce the engine performance. Clean the spark plug and check to be sure the spark plug gap is correct (0.6 - 0.7 mm).
Clean the air filter
See the Operating Instructions from the manufacturer of the engine (enclosed).
Storage during Winter
• Empty the tank
• Empty the carburettor:
-
To do so, start and engine and let it run until it stops by itself.
• Clean the scarifier thoroughly.
• Change the oil.
• Preserve the engine as follows:
-
Twist out the spark plug, and put one tablespoon of engine oil in the opening for the spark plug.
-
Slowly pull the starter rope all the way out (to distribute oil in the cylinder). Screw the spark plug back, but do not put the spark
plug connector back on.
• Store the scarifier in a cool and dry place.
Starting (Fig. B5/B6/B3)
•
Place mower on level ground, not onto high grass.
•
Accelerator lever (Fig. B5, 1) in START position.
•
Lift and hold safety bar (Fig. B5, 2).
•
Pull starter (Fig. B6) cord rapidly and return starter grip slowly. After engine started to run, move throttle lever to „Betrieb” (Fig. B5, 3).
• To stop engine:
Release safety bar (Fig. B5, 4).
• Starting of warm engine:
Throttle lever to „Betrieb” (Fig. B5, 3) (= running). If engine will not start after second attempt, place
throttle to „Start” (1) position and try again.
• Working:
Place lever slowly into forward position (Fig. B3, b). Work at slow walking pace.
Lawn condition
Working position
well kept lawns with stone-free, soft ground
Set tool exactly to ground height
stony, untidy lawns
Set tool to ground height
• Increase working height if stones are thrown up
unkempt, extremely mossy lawns
• Start with a high working height
• Do not overload appliance (increase working height if motor blocks)
• Cut vertically and crossways several times
• Re-sow with WOLF >>Loretta<< lawn seeds
