Application Planetary Grinding disc, Fwd, Rev

Setting up/Operation

Speed and direction setting is often a matter of per- sonal choice. Operators are encouraged to experiment to ﬁnd which settings best suit the given applications. The following table lists some suggested set-ups for different applications.

Application	Planetary	Planetary	Grinding disc	Grinding disc
	head	head	direction	speed
	direction	speed
Ceramic tile adhesive removal	FWD	6-7	FWD	8-10
Carpet glue removal	FWD	5-7	FWD	8-10
Epoxy paint removal	FWD	5-10	FWD	8-10
Rain damaged concrete	FWD	7-10	FWD	8-10
Smoothen exposed aggregate	FWD	7-8	FWD	8-10
Lippage removal in terrazzo/stone tiles	FWD	5-7	FWD	8-10
Concrete polishing with resin bond pads	FWD	10	FWD	8-10
PIRANHA™ scraper tool	REV	3-5	REV	3-5
FLEXOR™ ﬂexible heads	FWD	5-7	FWD	5-7
Bushhammer/Scarriﬁer tools	FWD	5	FWD	5-7
Re-grouting procedure during HiPERFLOOR™	FWD	8-10	FWD	3-5
process

IMPORTANT!

In the above table, FWD & FWD are listed together to indicate direction settings in the same direction (i.e. It can also be REV/REV). The only application where direction set- tings must be in the same directions and also direction speciﬁc is when using the PIRA- NHA™ scraper tools. In this particular ap- plication the setting must be in the REV/REV direction.

Direction of rotation

The correlation between FWD/REV & Clockwise/Coun- ter clockwise rotation can be said as follows if looking at the grinding discs from underneath the machine:

1.REV—Clockwise.

2.FWD—Reverse.

As mentioned, when the machine is in operation it will “pull” to one side. The direction of pull is determined by the planetary head direction of rotation. The head of the machine will pull to the right (and therefore, will be felt on the right hip of the operator) when the planetary head is set in the REVERSE direction.

This sideways pull can be very useful when grinding, particularly along a wall. Set the machine so that it pulls towards the wall, and then control the machine so it can just touch the wall. This will ensure a grind close to the wall or object.

Direction is also a matter of personal preference. It should be noted, however, that when both grinding discs and planetary heads are running in the same direction, a more powerful grinding force is created be- tween the diamond abrasives and ﬂoor being ground. The end result is higher productivity than when the discs are set to run in opposite directions. It is here that you will also experience the beneift of Dual Drive Technology™.

Production tip - To improve the cutting efﬁciency of diamonds, change directions on a regular basis. This will work both sides of the diamond crystals, keeping the abrasives as sharp as possible by creating maxi- mal exposure of the diamond crystal.

Once both a speed and direction have been nominated, switch on dust extraction or vacuum de- vice.

IMPORTANT!

It is highly recommended to use the Husq-

varna DC 5500 dust extraction system for complete dust control.

Standing behind machine with handlebars set as described earlier, apply a small amount of downward pressure on the handle. Switch the machine to run mode using the STOP/RUN switch on the control panel. The machine should start smoothly and acceler- ate to the selected speed over a period of 5 seconds
