OPERATION

The HRA21 may be used with the grass bag or discharge adapter. The following suggestions and rules are intended

to help you operate your Honda HRA21 under the

safest conditions possible. Be alert and exercise the

same care using the mower as you would using any

other power tool.

* Be especially careful when mowing uneven or rough

ground. The mower may tilt, exposing the blade, and hidden objects could be thrown by the blade.

Keep all four wheels on the ground.

* Use extra care when mowing around objects to

keep the blade from striking them. Never delibera-

tely mow over any object.

* Stop the engine immediately if the blade hits an

object or the mower starts to vibrate. Remove the spark plug cap (keep the wire away from the plug) and inspect for damage.

NOTE:

Mow across slopes.

Do not mow excessively steep slopes. Always push, never pull, a mower with the engine running.

Control direction by the handle, not by foot pressure on the mower housing. Keep a firm hold on the handle and walk, never run, with the mower. Don’t lag behind the machine or let it pull you.

(SDA and SDAW TYPES) Do not use the drive

clutch when maneuvering around trees, etc. Release the clutch and push the mower while using the ROTO-STOP for better directional control.

BEFORE YOU START THE MObVER

1. Check the engine oil level.

pY5V-l

* Engine oil is a .major factor affecting engine per-

formance and service life. Non-detergent or veget-

able oils are not recommended.

* Running the engine with insufficient oil can cause

serious engine damage.

Use Honda-&troke, or an equivalent high deter-

gent, premium quality motor oil certified to meet or

exceed U.S. automobile manufacturers’ requirements

for service classification SE or SF. (Motor oils classified SE or SF will show this designation on the

container.) SAE low-40 is recommended for general, all temperature use. If single viscosity oil is used, select the appropriate viscosity for the average temperature in

your area. A. With the mower on a level ‘surface, remove the oil

filler cap/dipstick using a screwdriver as illustrated.

B. If the level is low, add the recommended oil to

the “Upper” mark on the dipstick. Do not overfill; excess oil will result in power loss and smok-

ing.

UPPER OIL LEVEL LOWER OIL LEVEL

2. Check the fuel level. Use regular or unleaded automotive gasoline of 86

pump octane or higher. Never use an oil/gasoline mixture or dirty gasoline.

Avoid getting dirt, dust or water in the fuel tank.

* Gasoline is extremely flammable and explosive un-

der certain conditions. Refuel in a well ventilated area with the engine stopped.

* Do not smoke or allow flames or sparks in the area

where the mower is refueled or where gasoline is stored.

* Be careful not to spill fuel when refueling. Fuel

vapor or spilled fuel may ignite. Make sure the

area is dry before starting the engine.

* Do not overfill the tank and make sure the filler

cap is securely closed after refueling.

* Refuel when the engine is cold.

-1 Gasoline substitutes, such as gasohol etc., are not

recommended, they may be harmful to the fuel system cov-

ponents.
