SPARKING PLUG
Never remove the spark plug or the igni- tion lead when checking to see if there is any spark, always use an approved test instrument.
Clean the sparking plug regularly (every 100 hours of use). Use a wire brush for cleaning.
Change the sparking plug if the electrodes are ex- cessively burnt or if the plug is damaged. The rec- ommendations of the engine manufacturers are as follows (fig. 24):
Briggs & Stratton: Champion J19LM (RJ19LM). Spark gap 0.76 mm.
Honda GCV: NGK BPR6ES.
Spark gap 0.7 - 0.8 mm.
BATTERY (*)
Electrolyte in the battery is toxic and corrosive. It can cause serious corrosion damage etc. Avoid all contact with skin, eyes and clothing.
In normal use during the season, the battery is charged by the engine. If the engine cannot be started with the starter key, it may be because the battery is “dead”.
Remove the battery by releasing the the battery as- sembly from the mower using a screwdriver (fig. 25). Connect the enclosed battery charger to the battery, and then connect the charger to a wall socket and charge for 24 hours (fig. 26).
After charging, connect the battery's contactor to the engine's contactor and reinstall the battery as- sembly (fig. 27). Note! The battery charger must not be connected to the engine terminal. The en- gine cannot be started by using the charger as a source of power supply, and the charger will be damaged.
WINTER STORAGE
Remove the battery and store for the winter well- charged (see above) in a dry and cool place (be- tween 0° C and +15° C). At least once during the winter storage period the battery should be mainte-
Before the start of the season the battery should be charged once again for 24 hours.
ADJUSTING THE CLUTCH CABLE (*)
If the drive does not engage when the coupling clamp is pressed against the handle, or if the lawn mower feels cumbersome or slow, the reason may be that the coupling in the transmission slips. To rectify this situation, adjust the clutch cable as fol- lows:
1.Remove the transmission cover by unscrewing the screws S (fig. 28).
2.When the clutch loop is released it should be possible to pull the mower backwards without any resistance. If this is not the case, loosen the locking nut U and screw in the nipple T until the mower can be moved backwards (fig. 29).
