Remove the fan casing. Clean the cooling fins on the cylinder, the fan and the rotating protective grille. Clean more frequently if mowing dry grass.
BATTERY
The battery is a
On delivery, the battery is in the accessories box.
The battery must be fully charged before being used for the first time. The battery should always be stored fully charged. If the battery is stored while totally flat it could sustain permanent damage.
If the machine is not going to be used for an extended period (more than 1 month), the battery should be charged, disconnected and then stored in a cool, safe place. Charge the battery completely before reinstalling.
The battery can be charged in two ways:
1.Via a battery charger (recommended). This must be a charger with constant voltage. The battery can be damaged if a standard type battery charger (for acid batteries) is used.
Stiga recommends battery charger with item no.
2.You can also allow the engine to charge the battery. In this case it is very important, above all when starting the machine for the first time and when it has not been used for a long time, to allow the engine to run continuously for at least 45 minutes.
Do not short circuit the battery’s terminals. Sparks occur which can result in fire. Do not wear metal jewellery which can come into contact with the battery terminals.
In the event of damage to the battery casing, cover, terminals or interference to the strip covering the valves, the battery should be replaced.
If the battery terminals are coated with oxide, they should be cleaned. Clean the battery terminals with a wire brush and grease them.
LUBRICATION
The machine’s articulated steering joint has four grease nipples that should be lubricated with universal grease after every 25 hours of operation (fig. 20).
Note: The fourth grease nipple is not shown on the picture. It is located on the underside, on the flexible axle’s front bearing.
Lubricate the steering chain with chain spray a couple of times per season.
Lubricate the steering chains with chain spray a couple of times per season. If the steering chains are really dirty, dismantle them, wash them and then grease them once more.
The front wheel hub has grease nipples that should be lubricated after every 50 hours of operation (fig. 24).
Apply universal grease to all the plastic bearings a couple of times per season.
Apply a coating of engine oil to the tension arm joints a couple of times each season.
