pushed all the way up on the hose barb.
b) DRAINING RECOVERY TANK
WARNING!
If the recovery tank is not drained when the solution tank has been refilled, foam or
water may enter the float shut-off mechanism and cause damage to the vacuum
motor
NOTE
If you are storing the machine for any period of time, always leave the clear
recovery tank lid off the tank so the tank can dry completely and smell fresh. Any
time scrubbing is completed, or when refilling solution tank, the recovery tank
should be drained and cleaned.
1. Remove the drain hose from the holder, and place the drain hose over the floor drain. Twist off the drain hose
plug to begin the draining process.
2. Clean the recovery tank after every use. Use a fresh water hose to rinse out the recovery tank. Be careful not to
