Maintenance; Every 5 Hours; Every 25 Hours - Simplicity SERF 535 Owner's Manual

MAI IMTE N AIM C E,
Regular maintenance of your Simplicity tractor will great¬
ly increase its useful life and reduce repair costs. See your
Briggs and Stratton manual for engine maintenance in ad¬
dition to the steps listed here. »
Every Five Hours
Before starting the engine and at least once every five
hours check the oil level in the engine crankcase. Turn the
inspection-fill plug counter clockwise to remove. Main¬
tain the oil at the full level. (See Figure 20).
4. Genera! Lubrication: The five grease fittings on your
tractor should be greased with a lithium base automotive
type grease. Remove all dirt, grit and paint from the fitting
before greasing. A few drops of engine oil should be ap¬
plied to the points indicated. Do not allow oil to get on
belts or pulleys. (See Figures 21, 22 & 23).

Every 25 Hours
Every 25 hours or oftener under extremely dusty condi¬
tions: All attachments should be removed from the tractor
and the following maintenance procedures performed:
1. Clean the Cooling System: In order to clean the engine
cooling system, it will be necessary to remove the four
thumb screws holding the hood and remove the hood from
the tractor, lifting up and forward to clear the steering
wheel. Clean all grass, chaff and dirt from the engine fins
and shrouds.
2. Change Engine Oil: Drain the crankcase when the en¬
gine is warm. Remove the drain pipe cap until all oil is
drained, then replace cap and tighten securely. Refill the
crankcase with a high quality detergent oil classified MS.
Summer (above 40°F.) use SAE 30. Winter (below 40°F.)
use SAE 5W-20 of SAE 10W. IT IS VERY IMPORTANT
THAT THE ENGINE IS SERVICED ACCORDING TO
THE SEASON AND TEMPERATURE IT WILL BE USED
IN.
3. Clean the Air Cleaner: Turn the screw on the air cleaner
cover counter clockwise to loosen. Remove cover and
foam element. Wash the foam air cleaner element in Kero¬
sene or liquid detergent, squeezing several times and dry it
thoroughly. Saturate it with engine oil, squeeze several
times to distribute the oil and remove excess and reinstall.
Make certain the lips of the filter are in position when in¬
stalling.
