OPERATING INSTRUCTIONS
HOLDING THE UNIT
WARNING: Always wear eye, hearing, foot and body protection to reduce the risk of injury when operating this unit.
Before operating the unit, stand in the operating position (Fig. 16).
Check for the following:
• The operator is wearing eye protection and proper clothing.
• Both hands are holding the handle bar firmly.
• The edger wheel adjusted for proper cut depth as shown in
Figure 17 and edger positioned as shown in Figure 16.
ADJUSTING EDGER CUTTING DEPTH
1.
Grasp the depth adjustment lever located beside the front wheel (Fig 17).
2.
To raise the cutting blade, move the lever toward the front of the wheel bracket (Fig. 17). Lowering the wheel decreases the cutting depth.
3.
To lower the cutting blade, move the lever toward the rear of the wheel bracket. Raising the wheel increases the cutting depth.
TIPS FOR BEST EDGING RESULTS
• Do not force the edger. Edge the first time at a lesser depth,(No more than 1/2” depth cut per pass), then do the area again with a deeper setting.
• Walk the edger at a slow, even pace.
• Check the blade condition. As it wears it becomes smaller, thus reducing the cutting depth performance. Replace with a new blade when the blade has worn to the blade’s wear limit holes (Fig. 18).
ADJUST BELT TENSION
If blade fails to turn when the bail is pulled, then:
1.
Locate small thumb wheel on top of the belt housing (Fig. 17).
2.
Turn the wheel clockwise 1 revolution to increase the tension on the belt.
3.
Try pulling the bail and see if the blade turns. If not, repeat step 2 until the blade turns.
