Throttle Control
To maintain the correct fluid level in the battery, top with distilled water only to the high level mark shown on the
battery.
Note:
If the I.P.D is not used for at least five (5) hours a month, the battery will discharge and could sustain permanent
damage. Do not allow the battery to discharge. Regularly trickle charge with a current not exceeding 3 amps per hour
for three (3) to four (4) hours to prolong battery life. Keep the outside of the battery, especially the terminals, clean and
dry and check the battery is held securely.
Dry Battery:
When initially charging a new DRY battery, each cell must be filled to the high level shown on the battery
with an electrolyte (dilute sulphuric acid) with a specific gravity of 1.26 at 20°C to 30°C. The battery must then be
allowed to stand for thirty (30) minutes before charging at a rate not exceeding 3 amps for four (4) hours.
Warning:
Persons not trained in the proper procedure to transfer fluids containing acid or do not have the
necessary safety equipment on hand in case of a spill or exposure, should not attempt this procedure. Contact the
battery manufacturers local agent or an authorized Greenfield dealer.

Change the engine oil after the first five (5) hours. Change more often in heavy work or dusty conditions. Drain the
engine oil whilst the engine is warm, then replace. Fill to the full mark indicated on the dipstick. Do not overfill. Refer
to the specific manufacturers book to confirm oil and oil filter recommendations and the precise method of checking
the oil level.
The components of the gearbox have been lubricated prior to the gearbox being sealed at the factory. The shafts run
in large sealed ball bearings. No further lubrication of the gearbox is required.
Lubricate all other pivoting joints, lever points, and slides with engine oil.
Lubrication

Maintenance
Service the air filter as per the specific engine manufacturers book. Clean or replace more often in dusty conditions.
Never operate the engine without the air filter correctly and securely fitted, rapid and expensive wear will occur.
Air Filter
There are two (2) sizes supplied. The smaller set is for slow speed, heavy grassed areas, confined or uneven areas. The
larger set is for flat, larger, regularly mown areas. To change the drive dogs, disengage the drive, stop the engine and
disconnect the spark plug lead to prevent accidental starting. Remove the nyloc nut and washer from the end of both
drive shafts and slide off the drive dogs. Fit the new drive dogs onto the drive shafts, making sure that the recess in the
end of the dogs engages over the pins in the drive shaft. Refit the washers, nyloc nuts, and reconnect the spark plug
lead.
Drive Dogs
