IMPORTANT SAFETY INSTRUCTIONS

MAINTENANCE

1.Shut off fuel while storing or transporting. DO NOT store machine or fuel container inside where fumes may reach an open flame, spark or pilot light such as in a water heater, furnace, clothes dryer or other gas appliance. Allow engine to cool before storing machine in an enclosure. Store fuel container out of the reach of children in a well ventilated, unoccupied building.

2.Clean grass and debris from engine, mufflers, drives and cutting units to help prevent fires. Clean up fuel, oil and excess grease.

3.When draining fuel tank, drain fuel into an approved container outdoors and away from open flame.

4.Check brakes frequently (if equipped); adjust, repair or replace as needed.

5.Keep all bolts, nuts and screws properly tight. Check that all cotter pins are in proper position.

6.Always provide adequate ventilation when running engine. Exhaust gases contain carbon monoxide, an odorless and deadly poison

7.Disconnect battery before performing maintenance or service. Cranking engine could cause injury. Disconnect negative (black) cable from battery first and positive (red) last. Reconnect positive first and negative last. Charge battery in an open well ventilated area, free from spark and flames. Unplug charger before connecting or disconnecting from battery. Wear protective clothing and insulated gloves.

8.Park machine on level ground. DO NOT work under machine without safety blocks.

9.Service engine and clean, adjust or repair only when engine and blades are stopped. Remove key. Remove spark plug wire(s) from spark plug(s) and secure wire(s) away from spark plug(s).

10.DO NOT change engine governor speed settings or overspeed engine. DO NOT make adjustments with the engine running.

11.Lubricate machine at intervals specified in manual to prevent controls from binding.

12.Mower blades are sharp and can cut. Wrap the blades or wear heavy leather gloves and use CAUTION when handling them. DO NOT straighten or weld blades, only replace them.

13.DO NOT test for spark by grounding spark plug next to spark plug hole; spark plug could ignite gas exiting engine.

14.Carefully release pressure from components with stored energy.

15.Have machine serviced by an authorized SNAPPER dealer at least once a year and have the dealer install any new safety devices. DO NOT allow untrained personnel to service the machine.
