Husqvarna PG 680

De Husqvarna PG 680 is een uitstekende keuze voor zowel grote als kleine toepassingen en in het bijzonder voor verhuur doeleinden. Omdat hij kleiner is dan de PG 820, is de PG 680 vermaard vanwege zijn wendbaarheid en gebruiksgemak, zonder dat hij daarvoor aan vermogen en output heeft hoeven inleveren.

Unpacking

Unpacking

To prevent damage to the Grindng shrould when unpacking and transporting ensure to follow the recommended procedure as outline in the supporting video.
Setup workspace

Setup workspace

Position grinder on the working area. Set handle in upright position (illustrated right).

Pull back on handle using the kicker bar to lift grinding head off the ground.

Lay machine back on the ground.

WARNING!

Ensure STOP/RUN switch is in STOP position as unintentional starting of machine while changing discs can result in serious injury.
Assembling diamonds

Assembling diamonds 1/3

Have a set of gloves ready, as diamonds can get very hot during dry grinding applications.

WARNING!

Ensure STOP/RUN switch is in STOP position as unintentional starting of machine while changing discs can result in serious injury.

Assembling diamonds 2/3

As different applications require different selections of diamond tools, there will be many occasions when the grinding discs need to be changed.

Place diamonds as shown in the Redi Lock™ diamond holder disc and secure by tapping lightly. Assembly discs on planetary head lock screws by slightly rotating it.

Note

When using the machine, each grinding head should always have the same diamond type and number of diamonds as the other grinding heads. Each grinding head must have diamonds the same height as the other grinding heads.

WARNING!

Ensure STOP/RUN switch is in STOP position as unintentional starting of machine while changing discs can result in serious injury.

Assembling diamonds 3/3

Once new diamonds have been attached, reverse procedure to lower machine to ground.

Adjust rubber skirt so that a good seal is established between the floor and head of the machine. Ensure join in skirt is at the front of the machine to allow for better air flow. Setting of the skirt is essential to obtain good dust extraction and minimise the possibility of airborne dust.

WARNING!

Ensure STOP/RUN switch is in STOP position as unintentional starting of machine while changing discs can result in serious injury.
Adjusting Handlebar

Adjusting handlebar

Set handle to most comfortable working height using adjustment lever.

Note

It is recommended that this height be set as close as possible to the height of the operator’s hip bone. When the machine is running, there can be a slight grinding force/pull to one side that can be felt through the handlebars. Use the hip to resist this force instead of trying to control this through the arms (such positioning will be much easier for the operator using the machine over prolonged periods of time).
Connect DC

Connect DC

-Connect the hose to the PG Grinder.

-Connect the hose to the DC.

-Attach the plastic bag to the DC, if this is not already in place.

-Plug in the power cable to the DC.

Note

The power cable dipictad in the footage may vary from region to region.
Powering up machine

Powering up machine

Ensure the STOP/RUN switch is set on Stop (rotate counter clockwise).

Plug power supply to machine. Only turn power on at plug once fully connected.

Disengage Emergency Stop button (twist clockwise).

Depress Power button. On doing so, a soft “clunk” should be heard to come from within the electrical cabinet. This indicates the line contactors have engaged, supplying power to the drives/frequency converters.

Note

The power cable dipictad in the footage may vary from region to region.

Note

Always have the DC Vac running before starting to run the Grinder
Smooth start

Smooth start

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 accelerate to the selected speed over a period of 5 seconds.
Setting speed and rotation

Setting Speed and rotation 1/2

On the control panel there is a FORWARD / REVERSE and Speed dial. When starting the machine for the first time on any given application, it is advised that the speed setting should not exceed 7 on start up. As the application allows speeds may be increased during operation.

The machine should start smoothly and accelerate to the selected speed over a period of 5 seconds.

Setting Speed and rotation 2/2

Speed settings should be adapted to the specific application. This will differ from application to application and tools configurations.

For example having a faster satalite speed and slower planetary speed will allow the diamond tools to concertrate in the same area for a longer period of time, giving a higher stock removal rate.

In order to achieve maximum effiency different settings will be required.
Dual drive Technology

Dual Drive Technology™

Two types of planetary effects can be achieved with Dual Drive Technology™ – counter rotation and same direction rotation. Each of them creates a different dynamic under the machine and therefore, a different result in the grinding.
Counter rotation

Counter rotation 1/2

While in counter rotation, the diamonds closer to the centre of the machine move in the direction to the planetary rotation.

The diamonds toward the outside move away from the direction of planetary rotation.

As the inner diamonds are being accelerated in the direction of planatery rotation they grind more aggressively creating an inner band where the machine cuts more effectively.

Counter rotation 2/2

When the machine is moved forward, the middle zone is ground more thoroughtly then the outer zones. The end result is a deeper cut through the middle zone when compared to the outer zones.
Same direction rotation

Same direction rotation 1/2

While in same direction rotation, the diamonds closer to the centre of the machine move in the opposite direction to the planetry rotation.

The diamonds toward the outside move in the direction of planetary rotation.

As the outer diamonds are being accelerated in the direction of planatery rotation they grind more aggressively creating an outer band where the machine cuts more effectively.

Same direction rotation 2/2

When the machine is moved forward, the middle zone is still ground more thoroughtly then the outer zones but not as much as in the case of counter rotation. The end result is a more even cut through the middle zone when compared to the outer zones, which is less prominate then in counter rotation.
Grind-pattern relevancy

Relevance of grindning patterns

All planetary grinders remove more stock from the middle of the grinder. Always overlap the outer zones to ensure efficient and clean grinding.

Remember to change the grinding rotation each pass to maintain a uniformed direction over the floor.
Grinding close to a wall

Grinding close to a wall

When the machine is in operation it will slightly pull to one side. This force is determined by the planetary head rotation. When the head of the machine pulls in to the wall the operator will get a much closer cut to the wall.

A comfortable operating position should allow the handle bar to rest firmly against the operator´s hip.
Diamond selection

Diamond selection

The way diamond segments are set-up on the grinding heads of the machine will also greatly influence the performance of the machine, the productivity levels and also the finished floor quality.
Application reference
Full set vs Half set

Full set vs Half set 1/3

There are basically two types of diamond configurations that can be used when using the Husqvarna PG grinders:

Full set of diamonds. When there are diamonds placed at all positions on the diamond holder discs.

Half set of diamonds. When there are diamonds placed at each alternating positions on the diamond holder discs.

By changing the way the diamonds are set-up on the diamond holder discs, an operator can significantly affect the performance of the machine and therefore the finished product.

Full set vs Half set 2/3

A full set of diamonds will cut a flater floor when compared to a half set of diamonds.

The full set will remove all the high spots instead of carring with the surface of the floor and droping down into the low or softer spots.

With a full set of diamonds the highest level of flatness will be achivied.

Full set vs Half set 3/3

A half set of diamonds will follow the surface of the floor.

The grinder can be placed on an uneven surface and yet still find a stable footing. The half-set diamond configuration should be used when a flat floor is not required.

The half set will carry over the high spots and into the low spots, which is ideal to remove floor coatings or glues where optimum flatness is not the overall objective.
Diamond vs single segment

Diamond vs single segment 1/3

As well as using full set and half set, the operator can also choose from double or single segment tools. This will enable the operator to have control over both his tool economy and productivity.

Double segments: A double segment tool consists of two diamond segments on one Redi Lock™ shoe.

Single segments: A single segment tool consists of one diamond segments on one Redi Lock™ shoe.

Diamond vs single segment 2/3

Double segments are more commonly used as there is less preasure on each diamond segment resulting in lower cost and longer tool life. In principle double segments are used on softer concrete to prevent unwanted excess removal of the concrete stock.

Diamond vs single segment 3/3

A single segment is more commonly used on very hard surfaces as this increases the grinding pressure per diamond segment. This will result in a higher productivity and more aggressive concrete stock removal.

A significantly shorter tool life can be expected when using single segments due to the increase in segment preasure.
