• • • • • • Now try moving the hand control levers, one at a time, forward and backward. Check to see if the wheels move forward and backward according to position of the levers. If not, service the hand control system. If the wheels stop when the hand controls are in the neutral position, the parking brake should now be applied. Before testing the blade clutch/brake operation, make sure the area is clear and there is nothing vulnerable to possible thrown objects from under the mower.

SAFETY INSTRUCTION MANUAL TO WRIGHT MOWER USERS & OWNERS: READ THIS MANUAL BEFORE USING. PLEASE BE CAREFUL! INTRODUCTION This mower is built to the highest standards in the industry.
WARNING User Clothing: DO NOT operate the mower while wearing sandals, tennis shoes, sneakers, or shorts. Always wear long non-baggy pants. Wear high-top leather work boots with thick, textured tread, soft-rubber soled at all times. Hard or smooth soled shoes are too slippery for a good footing on mower platform. NEVER wear loose-fitting clothing or jacket pockets that can get caught to the handlebars or control levers of any mower you drive.
• Know the controls and how to stop quickly. • Before attempting to start the engine, follow all starting instructions below and in the engine operator’s manual. • Look behind before backing up. • Before leaving the operator’s position, even momentarily, turn off the blade clutch engagement switch and apply the parking brake. Keep others from coming near the mower. Get back on the mower as soon as possible.
Avoid this angle, as it has the least advantage for the Sentar. Recommendations for this angle: • Stretch your arms out straight while holding onto the stationary handlebar and sit back as far as you can on the seat. This adds more of your body weight to the drive wheels for more traction. • Do not change speed suddenly to minimize the tendency of going into a slide. Accelerate and decelerate gently.

NEVER store the equipment with gasoline in the tank inside a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure. WARNING Hydraulic Safety: Keep body and hands away from pin holes or fittings that eject hydraulic fluid under high pressure.

How to Change the Speed/Sensitivity Adjustment The controls are initially set with the Speed/ Sensitivity Adjustment in the faster, more sensitive position. If an operator is not completely familiar with mower operation the operator may desire to decrease the ground speed approximately 25-30%. The slower setting has a corresponding decrease in the sensitivity of the controls.
about 10 seconds apart. If the blades do not start and stop in a few seconds each time, service the blade brake system or contact your local Wright dealer.
