TILLERLUBRICATION

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.

CHECKHARDWARE

At leastevery 10 operating hours, check the unit for loose or missing hardware (screws, bolts, nuts, hairpin cotters, etc.). Loose or missing hardware can leadto

equipmentfailure, poor performance or oil leaks.

Besure 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.

Figure 5-1: Lubricationpoints.

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 Figure5-1 as described below.

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

•Removewheels, clean wheel shaft (A, Figure 5-1) andapply thin coating of greaseto shaft.

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

•Removetines, clean tine shafts (C, Figure5-1) and inspect for rust, rough spots or burrs (especially around holes). File or sand smooth and coat ends of shaft with grease.

•Oilthe threads on the handlebarheight adjustment screw (D, Figure5-1).

•Oilthe threads on the handlebarattach- ing screws (E, Figure 5-1).

CHECKTIREPRESSURE

Checkthe air pressure in both tires. Deflateor inflate both tires evenlyto 15-

to-20 PSI (pounds per square inch). Be sure that both tires havethe same air

pressure or the unit will tend to pull to oneside.
