MAIN BROOM SERVICE INSTRUCTIONS
TO CHECK THE MAIN BROOM SWEEP PATTERN
Check the main broom sweep pattern after changing the broom or when poor sweeping performance is encountered
while sweeping.
1. While the machine is not moving, lower the main broom to the SWEEP position and let machine sweep in one spot
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.”
WARNING

position and removing the right side panel cover.
