OPERATING INSTRUCTIONS and parts explosions CRT Models OperatioN PRE-START INSPECTIOn 1. Make sure all safety guards are in place and all nuts and bolts are secure. 2. Check oil level in engine crankcase. See your engine manual for procedure and specifications. 3. Inspect air cleaner for cleanliness. See your engine manual for procedure. 4. Check the fuel supply. Fill the fuel tank no closer than 1 inch from top of tank to provide space for expansion. See your engine manual for fuel recommendations. 5.
OPERATING INSTRUCTIONS and parts explosions CRT Models Idle Speed Use the “low” position on the throttle lever to reduce stress on the engine when tilling is not being performed. Lowering the engine speed to “idle” will help extend the life of the motor, as well as conserve fuel and reduce the noise level of the equipment. Operating Speed For normal tilling, set the throttle lever to “fast”. SHUTTING DOWN To stop the engine at any time, move throttle control to the off position.
OPERATING INSTRUCTIONS and parts explosions CRT Models Drive SAFETY Control LeverS FORWARD LEVER Engages wheels and tines into forward. Pulling the drive safety control lever labeled (FORWARD) toward the handlebar engages the wheels and tines. Releasing the lever stops the wheels and tines and brings the tiller to a complete stop. forward lever engaged ! CAUTION Do not operate both “FORWARD” and “REVERSE” drive safety control levers at the same time.
OPERATING INSTRUCTIONS and parts explosions CRT Models Wheel Lock pins (5055, R5055H) Place wheels in tilling position. 1. Remove lock pin. Align hole in axle with hole in wheel hub. 2. Insert lock pin through holes, fold lock pin ring to secure pin to axle. 3. Firmly lock wheel and axle together before tilling. 4. Repeat for other wheel. ! WARNING Never start engine or operate tiller with wheels in free-wheel position.
OPERATING INSTRUCTIONS and parts explosions CRT Models DEPTH REGULATOR LEVER Tilling depth is controlled by the height of the depth regulator lever. To adjust tilling depth. 1. Remove detent pin. 2. Raise the depth regulator lever to position tines at chosen tilling depth. 3. Align hole in depth regulator lever with hole in depth regulator bracket and replace detent pin. Depth Regulator Lever Down = Shallower tilling. Place the detent pin in the top hole of the depth regulator lever for shallowest tilling.
OPERATING INSTRUCTIONS and parts explosions CRT Models Tilling Tips The key to successful tilling is to begin with a shallow cut on the first pass, and then work an inch or two deeper on each successive pass. • Tilling depth will vary with ground conditions. • When beginning to till in unbroken ground or in extremely hard soil, set the detent pin in the highest hole of the drag stake (follow instructions under Tilling section). This will allow for shallow tilling.
