FOLDING HANDLE

This unit is equipped with a folding upper handle for easier storage and transportation. The handle can be folded by sliding the handle lock loops(item 28) up. This releases the upper handle, allowing it to be folded over the unit.

HANDLING & TRANSPORTING

This unit requires two people to lift it. With the handle in the folded position, lift holding the lower handle and belt/ shaft guard one on each side of the machine. Secure the machine in place during transport.

The depth of the blades can be raised or lowered by rotating the knob on the top of the adjustment lever. The blades are lowered by rotating the knob clockwise, and raised by rotating the knob counter-clockwise. The relative depth of the blades can be gauged by using the depth scale located on the right front corner of the engine base. With new blades installed the depth can be estimated as follows: 2.5 on the scale is even with the ground, 3 is equal to 0.25" deep, and 3.5 is equal to 0.5" deep

BLADE POSITION & DEPTH CONTROL LEVER

The blades can be raised or lowered into the ground by height adjusment lever on the engine base. The height adjuster lock lever must be pushed back against the adjustment lever in order to lower the blades into the ground. The resulting blade depth can be adjusted higher or lower.
