5.13.4 Checking Engine Coolant Strength
Check the anti-freeze in the pressurized coolant tank with a tester every year, preferably before off-season
storage. Anti-freeze is essential in any climate. It broadens the operating temperature range by lowering the
coolant freezing point and by raising its boiling point. Anti-freeze also contains rust inhibitors and other additives to
prolong engine life.
IMPORTANT:
If anti-freeze strength is not adequate, do NOT drain cooling system to protect against freezing. System may not
drain completely, and damage from freezing could still result.
CAUTION
To avoid personal injury from hot coolant, do NOT turn cap until engine cools.
DANGER
To avoid bodily injury or death from unexpected startup of the machine, always stop the engine and remove
the key from the ignition before leaving the operator’s seat for any reason.
1. Shut down the engine and remove the key.
2. Open the hood. Refer to 5.3.1 Opening Hood, page
