while sweeping.

for a short period.
2. Before moving machine, move main broom lever to the OFF position and move the sweeper forward until you can
see the pattern left by the main broom bristles on the floor.
3. Check the width of the pattern on the floor to determine if the main broom requires adjustment.
- A normal sweep pattern left on the floor will be between one and two inches wide.
- A pattern that is more than two inches wide indicates the broom linkage needs to be adjusted “UP.”
- A pattern that is less than one inch wide indicates the broom linkage needs to be adjusted “DOWN.”
