5.5 ENGINE COOLING
The engine is air cooled. Air must circulate freely
around engine and over cooling fins on cylinder head
and block to prevent overheating.
Once a year or every one hundred (100) operating
hours (more if conditions require) clean engine fins and
external surfaces of engine of dust, dirt, and oil
deposits which can contribute to improper cooling.
Keep Areas within Heavy Line Clean of all Debris
(Figure 16).
5.6 SPARK PLUG
Spark plug should be cleaned or replaced and gap
reset to .030" every 100 hours of operation or yearly
whichever comes first.
To clean, remove debris from area around spark plug
base. Remove spark plug from engine. Scrape and
wash with a commercial solvent. DO NOT blast clean.
NOTE: Sparking can occur if wire terminal does not fit
firmly on spark plug. Reform terminal if necessary.
5.7 BATTERY (ELECTRIC START MODEL)
A 12 volt, 2.5 ampere hour sealed lead acid battery is
supplied with unit. Engine alternator will normally keep
battery fully charged with a 3 to 5 minute start/run
cycle.
IMPORTANT: Use battery supplied only. DO NOT
attempt to "jump start" mower.
If battery discharges, use a 5 to 10 minute start/run
cycle to recharge battery, or use a battery charger (a
battery charger, kit number 71104300, is available from
Ariens). An engine run time of at least 8 hours is
required to charge a fully discharged battery.
To charge with Ariens battery charger, connect charger
plug to mating plug on battery (not engine) and plug
charger into 120 volt Alternating Current (AC) outlet.
Charge for 12 to 36 hours (battery may be charged for
up to 56 hours with no harmful effect).
CAUTION: Periodically clean muffler and
manifold areas to remove all grass, dirt and all
combustible debris. If engine muffler is
equipped with spark arrester screen
assembly, remove every 50 hours for cleaning
and inspection.
