CHECK HARDWARE

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key on electric start models.

Failure to follow these instructions can result in serious personal injury or prop- erty damage.

Figure 5-1: Lubrication points.

Proper lubrication of the tiller is an essen- tial part of your maintenance program. After every 10 operating hours, oil or grease the lubrication points shown in Figure 5-1 as described below.

Use a good quality lubricating oil (#30 weight engine oil is suitable) and a good quality general purpose grease (grease that has a metal lubricant is preferred, if available).

•Remove wheels, clean wheel shaft (A, Figure 5-1) and apply thin coating of grease to shaft.

•Grease back, front and sides of depth regulator lever (B, Figure 5-1).

•Remove tines, clean tine shafts (C, Figure 5-1) and inspect for rust, rough spots or burrs (especially around holes). File or sand smooth and coat ends of shaft with grease.

•Oil the threads on the handlebar height adjustment screw (D, Figure 5-1).

•Oil the threads on the handlebar attach- ing screws (E, Figure 5-1).

At least every 10 operating hours, check the unit for loose or missing hardware (screws, bolts, nuts, hairpin cotters, etc.). Loose or missing hardware can lead to equipment failure, poor performance or oil leaks.

Be sure to check the three end cap mounting screws located at the rear of the transmission (Figure 5-2). Lift the tine flap to service those screws.

CHECK TIRE PRESSURE

Check the air pressure in both tires. Deflate or inflate both tires evenly to 15- to-20 PSI (pounds per square inch). Be sure that both tires have the same air pressure or the unit will tend to pull to one side.
