AIR FILTER – CATALYTIC

CONVERTER (Pro20 Cat)

Clean the catalytic converter’s air filter every 3 months or after every 25 hours of operation, whichever comes first.

1.Remove the cover by pressing in the locking mechanism with a screwdriver etc. (fig. 18).

2.Remove the foam filter and wash it in liquid de- tergent and water. Squeeze dry. Do not oil the fil- ter.

3.Replace the filter and snap the cover into place.

SPARK PLUG

Only use a Briggs & Stratton sparking tester to check the spark in the sparking plug(s) (fig. 19).

Clean the spark plug after every 100 hours of oper- ation or once a season. For replacing a spark plug, a spark plug sleeve A and a torsion pin B are pro- vided in the accessories bag.

The engine manufacturer recommends:

Royal: NGK BPR5ES or DENSO W16EPR-U

President-Comfort-Pro16-Pro20: Champion RC12YC

Correct spark gap: 0.75 mm.

COOLING AIR INTAKE - ENGINE

The engine is air-cooled. A blocked cooling sys- tem can damage the engine. The engine should be cleaned at least once a year or every 100 hours of operation.

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 valve-regulated battery with 12 V nominal voltage. The battery is completely main- tenance free. You don’t have to check or top up the

electrolyte level.

On delivery, the battery is in the accessories box.

The battery must be fully charged be- fore 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 ex- tended 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. 1136-0602-01 which may be ordered by an au- thorised dealer.

2.You can also allow the engine to charge the bat- tery. 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 al- low the engine to run continuously for at least 45 minutes.

Do not short circuit the battery’s termi- nals. 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 bat- tery 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 uni- versal 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 flexi- ble axle’s front bearing.
