Adjusting The Spray Guard; Troubleshooting - HTC 130 Bedienerhandbuch

Adjusting the spray guard

The spray guard of the machine can be adjusted up and down about 15 by slackening the
fixing screws on the vacuum cover. The cover can also be modified by changing the size of
the rubber guard. Two sizes of rubber guard are supplied with the machine, 125 and 180 mm.
It is important that the spray guard is fitted in such a way that it is in contact with the floor, so
minimising the spread of dust and spray.
