Checking The Tire Pressure; Greasing And Lubricating The Machine; Checking The Parking Brake - Toro 70185 Operator's Manual

Checking the Spark Plug
1. Look at the center of the spark plug (Fig. 24). If you see
light brown or gray on the insulator, the engine is
operating properly. A black coating on the insulator
usually means that the air cleaner is dirty.

Important
Do not clean the spark plug. Always
replace the spark plug when it has a black coating, worn
electrodes, an oily film, or cracks.
2. Check the gap between the center and side electrodes
(Fig. 24) and bend the side electrode if the gap is not
correct.
Installing the Spark Plug
1. Install the spark plug and metal washer.
Note: Ensure that the air gap is set correctly.
2. Tighten the spark plug to 20 N m.
3. Connect the wire to the spark plug (Fig. 23).

Checking the Tire Pressure

Maintain the air pressure in the tires at 80 kPa. Check the
tire pressure after each use. Check the tires when they are
cold to get the most accurate pressure reading.

Greasing and Lubricating the
Machine
Grease the machine with a general-purpose grease after
every 25 operating hours or once a year, whichever occurs
first. Grease it more frequently when operating conditions
are extremely dusty or sandy.
1. Disengage the blade (PTO).
2. Shift the ground speed lever into Neutral.
3. Set the parking brake.
4. Stop the engine and wait for all moving parts to stop.
5. Remove the ignition key.
6. Lubricate the front wheels.
7. Wipe up any excess grease.

Checking the Parking Brake

Always set the parking brake when you stop the machine or
leave it unattended. Check the parking brake daily to ensure
that it holds securely.
1. Park the machine on a level surface.
2. Disengage the blade (PTO).
3. Set the parking brake.
4. Stop the engine and wait for all moving parts to stop.
5. Remove the ignition key.
6. If the rear wheels lock and skid when you try to push
the machine forward, you do not need to adjust the
parking brake. But if the rear wheels turn and do not
lock, you need to have an Authorized Service Dealer
adjust the parking brake.
