for wet processing (Danger!).

INTRODUCTION

1.1  FEATURES OF THE MACHINE

Fig. 1 (page 2) shows the most important assemblies which make up 

the HUMMEL. We recommend that you take some time to become 

familiar with the machine.

1.2  DESCRIPTION OF THE MACHINE

The HUMMEL belt sanding machine operates with a contact sand-

ing drum featuring a specially profiled rubber coating. The belt 

tensioning fixture with integrated automatic belt guidance is located 

vertically above the sanding drum. The work zone is covered by 

the machine housing and detachable side cover. On the machine 

housing, the electric motor is fixed in a motor bearing bracket. The 

plug for connection to the mains is located at the switch box of the 

motor. The motor switch with the switch positions START / WORK-

ING and TEST is located at the switch box. On the left under the 

belt guard is the belt drive unit. The machine is moved by means of 

a steering wheel at the back and two lateral wheels. Two handles 

are attached to the guide tube, where the drum lowering lever is 

also located and the cables and dust bag are attached.

The HUMMEL belt sanding machine is intended for dry use only. 
Never attempt to use the HUMMEL for any wet process (risk of 
fatal accidents)!

1.3  INTENDED USE OF THE MACHINE

The HUMMEL belt sanding machine is suitable for sanding wooden 

and cork floors, plastic skating rinks and tartan running tracks. A 

specially equipped version of the machine can be used to sand 

sheet metal surfaces.

Any application other than that described here is inadmissible 
without the consent of the manufacturer. Never use for wet sand-
ing processes!
