Husqvarna Understanding Oil Capacity and Maintenance for Your Lawn Mower

MAINTENANCE

•To check blade balance, you will need a 5/8" diameter steel bolt, pin, or a cone balancer. (When using a cone balancer, follow the instructions supplied with balancer.)

NOTE: Do not use a nail for balancing blade. The lobes of the center hole may appear to be centered, but are not.

•Slide blade on to an unthreaded portion of the steel bolt or pin and hold the bolt or pin parallel with the ground. If blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced.

TO CHANGE ENGINE OIL (See Figs. 15 & 16)

NOTE: Before tipping lawn mower to drain oil, empty fuel tank by running engine until fuel tank is empty.

1.Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.

2.Remove oil fi ll cap/dipstick; lay aside on a clean sur- face.

3.Tip lawn mower on its side as shown and drain oil into a suitable container. Rock lawn mower back and forth to remove any oil trapped inside of engine.

GRASS CATCHER

•The grass catcher may be hosed with water, but must be dry when used.

•Check your grass catcher often for damage or dete- rioration. Through normal use it will wear. If catcher needs replacing, replace only with approved replace- ment catcher shown in the Repair Parts section of this manual. Give the lawn mower model number when ordering.

GEAR CASES

•To keep your drive system working properly, the gear cases and area around the drive should be kept clean and free of trash build-up. Clean under the drive cover twice a season.

•The gear cases are filled with lubricant to the proper level at the factory. The only time the lubricant needs atten- tion is if service has been performed on the gear case.

NOTE: Multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, and you should check your engine oil level frequently to avoid possible engine damage from running low on oil.

Change the oil after every 25 hours of operation or at least once a year if the lawn mower is not used for 25 hours in one year.

Check the crankcase oil level before starting the engine
and after each fi ve (5) hours of continuous use. Tighten oil	12
plug securely each time you check the oil level.
