Starting The Engine - Nortrac XT20 Owner's Manual

2.3 Starting the Engine

WARNING: Before operating, the tractor should be checked over thoroughly to eliminate potential
accidents or breakdowns.
2.3.1 Engine Starting Preparations
Before starting the tractor, inspect for damaged or loose parts and
leakage.
Check the engine oil pan, the gearbox, the rear axle and the lube
oil level on the hydraulic system. The radiator should be filled
with antifreeze and the fuel tank should be full.
Check the control lever of the gearbox and the PTO control handle. The main shift lever, PTO control
handle and front drive axle control handle should be in the neutral position. The distributor control lever
should be in the lowering position.
Turn the fuel shut-down knob to fuel shut-down cable. The oil-spraying pump should be in the oil-
supplying position.
The throttle handle should be set at mid range.
Before starting a tractor that is new, recently overhauled or one that hasn't been used for a long time, first
discharge the air in fuel line to ensure that the diesel engine can start smoothly. The procedure is as
follows: Release the bleeder screw on the diesel filter, then discharge the air in fuel line from fuel tank to
the diesel filter using a hand pump until there are no bubbles in the discharged fuel. Then, unfasten the
bleeder screw on the fuel pump to release the air until there are no air bubbles in the flow of fuel.
IMPORTANT NOTES:
1. Clean contaminants from the radiator screen regularly to avoid over heating the engine.
2.3.2 The Starter
IMPORTANT NOTES:
1. Release the key immediately after starting of engine. The key will return to the ON position automatically
(see Figure Igniting Lock). If not released, the engine will continue to rotate the starter, causing damage.
2. The key should be turned no longer than 5 seconds and you should allow 15 seconds of time between
starts. To maintain the charging ability of the battery, do not try to start the tractor more than three times
and troubleshoot in order to find the problem.
