Before operating, review SAFETY PRECAUTIONS listed on page 6 of this manual.
Familiarize yourself with the operation of the unit and confirm that all controls
function properly BEFORE starting engine.
Locate the killing switch and assure you know how to STOP the unit.
Make sure hands, feet, and clothing are at a safe distance from any moveable parts
prior to starting.
Shrouds and guards are provided to protect the operator or structures in close
proximity to rotating hot engine parts. It is the RESPONSABILITY OF THE OPERATOR to
see that they are properly in place. NEVER operate this equipment without a guard.
OIL LEVEL - Check the oil level in the engine. For more information see "Lubrication"
under the engine "Owner's Manual" the "Maintenance" section of this manual. All
Equipment come without oil, running an engine without lubrication may damage the
engine.
AIR CLEANER - Check to ensure elements are in good condition and properly installed.
Review every decal with the OPERATOR.
FUEL SUPPLY - Engines on equipment require an automotive grade of clean, fresh,
unleaded or regular gasoline. All equipment’s come without gasoline and oil.
FUEL FILTER - Check to ensure element is in good condition... Replace if it is clogged or
damaged.
LUBRICATION POINTS –Grease wheels (4), Drive Shaft and bushing daily. ALGO MAS?
SPARK PLUG (GAS UNIT) –Check and clean spark plugs regularly. A fouled, dirty or
carbonated spark plug may cause difficulties starting and poor engine performance.
Set spark plug gap to recommended clearance. Refer to engine manual.
BELT TENSION –If there is excessive belt play, there will be a decrease in the
cutting/grinding performance, which could cause unit damages. The normal belt play
should be 3/8” to 1/2” which is measured by depressing the top section of the belt at
the belt guard mounting bracket location. When adjusting the belts, make sure that
the drive pulley is in aligned with the cage pulley.
POSITION –The only operating position for this scarifier is at the rear of the

Discount-Equipment.com

16
1. Check and clean spark plugs regularly. A fouled, dirty or carbonized spark plug
causes hard starting and poor engine performance. Set spark plug gap to
recommended clearance. Refer to engine manual.
BELT TENSION
1. If there is excessive belt play, there will be a decrease in the cutting/grinding
action, which could cause cage and machine damage. The normal belt play
should be 3/8” to 1/2” which is attained by depressing the top section of the
belt at the belt guard mounting bracket location. When adjusting the belt make
sure that the drive pulley is in alignment with cage pulley. Tighten all engine
mount bolts, adjust the two engine-stop bolts, and tighten lock nuts.
CUTTER CAGE REMOVAL/CHANGE
1. Make sure that the power source is disconnected. With gas models turn off fuel
supply to engine and disconnect sparkplug; unplug electric unit; disconnect air
supply on air unit.
2. Tilt machine back onto the handle. (If your unit is equipped with a Honda GX
engine, unit must be tilted forward to change cutters or cylinders will be
flooded with oil).
3. Facing the underside of the machine housing (figure 3-A) place a bar between
the cutter rods to jam cage C.
4. Remove end cap and with a 1” (26 mm) socket loosen and remove the shaft
by turning in clockwise direction or remove end cap and shaft guard to insert a
drift pin into the hole on the main shaft B and turn shaft clockwise to loosen and
remove shaft.
5. Disengage the cage from the drive pins by moving to the left. (The cage on the
Honda GX machines will move to the right). Remove cage.
EDGER CAGE REMOVAL
1. Make sure that the power source is disconnected. With gas models turn off fuel
supply to engine and disconnect sparkplug; unplug electric unit; disconnect air
supply on air unit.
2. Tilt machine back onto handle. (If your unit is equipped with a Honda GX
engine, unit must be tilted forward to change cutters or cylinders will be
flooded with oil).
3. Using a 15/16” socket or wrench, turn head of shaft (G) clockwise to loosen.
4. While turning the shaft outwards, cage will move towards the outer edge as
well. Free cage from locking pins on shaft by pushing cage back towards main
housing (A). Turn shaft out and move.
