Yazoo/Kees KIKW36150, KIKW48150, KIKW48170 manual Maintenance

MAINTENANCE

1.Engine oil level: Check daily with engine cold and on a flat surface. Remove the dipstick and wipe clean. Reinsert the dipstick all the way, but do not screw down. Remove the dipstick and check oil level. If oil level is low add oil. Use engine manufacturers specs for type of oil.

2.Mower blades: Stop engine and remove key. Inspect blades and sharpen or replace as needed. Check daily or more often if needed. The machine requires more power with dull blades and gives a poor cut. If blades get bent, replace them. Blades shouldn’t have any notches from hitting objects. The air foil on top of the blade should be sufficient to raise the grass for cutting. If blades are in good condi- tion, sharpen at an angle of 22 to 28 degrees about 2-1/2 inches in from the tips.

Blade Removal

NOTE: Protect your hands with gloves and/or wrap blade with heavy cloth.

•Remove blade bolt by turning counterclockwise.

•Install new or re-sharpened blade.

•Install and tighten blade bolt securely (90 ft./lbs. torque).

To Sharpen Blade

WARNING

When it is necessary to raise the mower for any repair or service, use jackstands to provide adequate sup- port. DO NOT rely on hydraulic or me- chanical jacks

Care should be taken to keep the blade bal- anced. An unbalanced blade will cause exces- sive vibration and eventual damage to mower and engine.

•The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower.

•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 the blade.

•Slide blade on to an un-threaded portion of the steel bolt or pin and hold the bolt or pin parallel with the ground. If the 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.

3.Safety interlock system: Check daily and never operate the mower if this system is not func- tioning properly.

4.Hardware: Stop engine and remove key thor- oughly inspect the entire machine for any miss- ing or loose hardware. Check daily.

5.Air cleaner: Stop engine and remove key. Re- move plastic cover and loosen wingnut on the air cleaner. Remove the foam pre-cleaner and wash or replace if needed. Inspect paper filter and replace if dirty. Check every 25 hours, daily if in very dirty conditions. Fuel efficiency, en- gine RPM, and available power goes down rap- idly if the air filter is dirty. Prolonged effects could damage the engine.
