3 GENERAL DESCRIPTION

Introduction

The HAMA Duo-Power 2.0 consists of the following parts:

• Frame with hoppe

• Electric motor

• Transmission

• Control panel

• Pump

• Plaster pump

• Skim coat pump

Frame

The frame serves as a base for the HAMA Duo-Power 2.0. A material hopper with a volume of 80

litres is built on to the frame, making it possible to spray plaster without interruption for a longer

time.

Electric motor

The Duo-Power 2.0 is powered by a 2.2 kW motor.

Transmission

The transmission ensures that the high rpm of the motor is converted into a lower speed with

higher torque so that different materials can be sprayed easily.

Control panel

The control panel contains all the parts that control the HAMA Duo-Power 2.0. One of these parts

is a frequency controller that slows the motor and even stops it as soon as you stop spraying.

Pump

The pump ensures that the aggregate to be sprayed from the hopper is pressurised at the

required pressure. The HAMA Duo-Power 2.0 is a machine that can be used for two main

purposes. The basic machine of the HAMA Duo-Power 2.0 was designed according to the 2-in-1

principle. Two different types of activities, plastering and skim coating, can be done with the same

basic machine by simply swapping the pump

• Plaster pump

The plaster pump was specially designed for spraying plaster materials. This low pressure

pump can generate a pressure of 60 bar with 8 litres per minute

• Skim coat pump

The skim coat pump was specially designed for spraying skim coat materials. This high-

pressure pump can generate a pressure of 140 bar with 4 to 5 litres per minute.

4 COMMISSIONING

Introduction

Check the HAMA Duo-Power 2.0 for possible transport damage at the time of delivery. Report

transport damage to the carrier and your supplier immediately.

Inspection of hopper

Prior to rst use, check whether the hopper is completely clean. During transport or storage,

items such as wood, coarse gravel, stones or nails could have landed in the machine. These items

could cause serious damage to the machine.

Set-up

Make sure that the machine is level prior to use.

Connection to a power supply

The HAMA Duo-Power 2.0 must be connected to a 230 V wall socket with earth connection and

must be fused for 16 A.

If no wall socket is available in the immediate area, no more than one fully extended extension

reel or extension cord with an earth connection and a minimum core thickness of 2.5 mm2may be

used.

Extension cords that are too long and lightweight can cause

undervoltage, causing the electric motor to burn out. HAMA advises

using extension cords with a minimum core thickness of 2.5 mm2.

The HAMA Duo-Power 2.0 can generate an operating pressure of 140

bar. Leaks due to damage to hoses and couplings can lead to physical

injury.

Never connect the HAMA Duo-Power 2.0 in combination with the

HAMA H455 compressor to the same fuse group. Both machines on

the same fuse group will cause an overload!

Extension reels must be fully extended in order to prevent re.

If the HAMA Duo-Power 2.0 is used in combination with the HAMA

H455 compressor or another equivalent compressor, each machine

must be connected to a separate fuse group of 16 A.

5 OPERATION

Introduction

This chapter provides information about operating the HAMA Duo-Power 2.0 in the plaster

application version as well as the skim coat version.

Safety

• All safety markings and hazard designations on the machine must be

clearly visible throughout the service life of the machine.

• Only people who have been trained specically for this are permitted

to operate the machine.

• Because compressed air and aggregate hoses could get bent over

sharp edges, serious damage could occur that can result in physical

injury. Hoses with kinks in them must be replaced immediately.

• Air hoses and aggregate hoses that are to be opened or uncoupled

must be depressurised rst.

• Persons rectifying blockages in an aggregate hose and spraying tools

(spray gun) must make sure that they and bystanders are not sprayed

with outgoing aggregates.

• Wear ear protectors. Working with the repair gun or being present in

the immediate vicinity of repair work may lead to hearing damage.

• Wear eye protection (safety goggles). The air pressure may cause

small hard or liquid particles to deect off the wall causing damage to

eyes.

• Wear a gas mask. Most plaster products contain solvents. This could

cause dizziness or even unconsciousness.

• The HAMA Duo-Power 2.0 must be connected to a 230 V wall socket

with earth connection and must be fused for 16 A. If no wall socket

is available in the immediate area of the workplace, no more than

one fully extended extension reel or extension cord with an earth

connection and a minimum core thickness of 2.5 mm2may be used.

Safety devices both on the outside of the machine and in the

hopper must be present and intact at all times as they where during

commissioning. In the event of damaged or lost safety devices, the

machine must not be used until it has been restored to its original state.

HAMA_DP2_UM-20151116-EN

5 OPERATION

The HAMA Duo-Power 2.0 may only be used in combination with a

compressor that generates a maximum operating pressure van 8 bar

such as the HAMA H455 compressor. Higher pressure can lead to

serious physical injury.

It is prohibited to stir in the hopper when the machine is operating.

Stirring tools may reach through the protective grid to moving parts and

cause damage or injury.

It is prohibited to aim the sprayer at parts of your own body or that

of others. Contact of the spray material with eyes can cause serious

irritation. Rinse eyes immediately by a health & safety ofcer or a doctor

if they are accidently sprayed.

5 OPERATION

5.1 Operation of plaster sprayers

1. Remove the lid from the hopper and ll the hopper with spray aggregate.

2. If a wringer is used, follow the following steps:

HAMA wringer:

a. Place the bag on the wringer

b. Position the handle of the bag between the rollers

c. Put pressure on the bag

d. Cut open the bottom with a knife

e. Turn the handle of the wringer

f. The aggregate will be deposited in the centre of the hopper

g. Clean the wringer well after use

Washing machine wringer:

a. Place the bag between the rollers

b. Cut open the bottom with a knife

5 OPERATION

7. Switch on the main voltage switch on the right side of the machine and press the green

“Reset” button.

8. Set the rotation direction switch to “1” or “ON”.

9. Keep the gun aimed in the hopper and open the gun. Turn the pressure regulation button to

position 4 and wait until the aggregate comes out of the gun. Allow the machine to warm up

until the pump is at the required temperature and set the rotation direction button to “0” or

“OFF”.

10. Turn the pressure regulation button to the 0 position and open the gun until the pressure

gauge indicates 0 bar.

11. Now attach the required nozzle.

12. Open the protective cover of the motor and position the V-belt on the centre pulley and

close the protective cover again.

13. Push the “RESET” button and set the rotation direction switch to “1” or “ON”.

14. Aim the gun into the hopper again and turn the pressure regulation button to a higher

position until the required spray distribution or aggregate ow is achieved.

If the pressure regulation button is turned open further but the motor

does not run faster, the maximum rpm has been reached. The pressure

regulation button may not be turned open even more because, when

the gun is closed, a very high pressure could arise, resulting in damage

to the hoses and possible injury to the operator or bystanders.

5 OPERATION

5.2 Conversion from plaster application to airless spraying

The HAMA Duo-Power 2.0 is a multi-purpose machine that can spray plaster as well as airless.

Depending on the version of the Duo-Power 2.0 ordered, the machine can easily be converted by

replacing the pump with another version. If you purchased the HAMA Duo-Power 2.0 as a plaster

application machine and you want to spray skim coat as well, you can convert it into an airless or

skim coat machine very easily by replacing the pump with a high-pressure pump.

All conversion steps necessary are described below so that you can be operational again within

20 minutes.

5.2.1 Dismantling process for conversion from plaster to airless

1. Remove all plaster from the hopper.

2. Spray with the aggregate hose until it is completely empty.

3. Rinse the hopper clean with a few litres of water and spray out the dirty water. Repeat

this once again and add a small amount of washing-up liquid to prevent corrosion of the

pump. If necessary, clean the hopper with water and a paper cleaning cloth. The hose can

be cleaned easily with a sponge ball.

4. Depressurise the machine completely and decouple the aggregate hose from the machine.

5. Press the emergency stop and remove the connection cable from the machine.

6. Loosen the three nuts on the nosepiece and remove the nosepiece and the sensor housing.

Clean them both with water..

7. Next, the stator together with the rotor can be removed by turning the entire unit back

and forth while at the same time pulling on the stator. The bayonet connection on the rotor

will now come off easily.

After removing the pump, we recommend that the rotor of the stator

be turned and both parts be cleaned and maintained well. If this is

not done, both parts could get stuck because of plaster residue and

become unusable!

ATTENTION

HAMA_DP2_UM-20151116-EN

5.2.2 Assembly process for conversion from plaster to airless

1. Check that there is still no pressure or power on the machine and that the emergency stop

is still pressed in as described in the dismantling steps.

2. Remove the safety grill from the interior of the hopper.

3. Install the three thread rod extensions with the nut.

4. Position the bottom and top pump bracket by fastening the seven locking bolts. Only the

three bolts on the shores can now be tightened. The other four bolts should not be

tightened until the stator is in the correct position.

5. Remove the short shaft in the hopper, clean it with water and put it back in the machine.

6. Place the skim coat stator together with the rotor that has been inserted in the machine and

the adaptor ring.

7. NOTE: the bayonet connection of the rotor must be on the same side as the yellow arrow

on the stator.

8. Insert your hand into the hopper and support the short shaft until the bayonet connection of

the shaft is connected to the rotor.

9. Now reinstall the safety grill in the hopper.

10. Slide the sensor housing over the thread rods on the right side and the protruding catch on

the hose side.

11. Place the O-ring in the sensor housing and slide the skim coat nosepiece over the thread

rods. Tighten the entire unit with the washers and nuts with a torque of 30 Nm.

12. Now tighten the last four bolts of the pump brackets and mount the aggregate hose on the

machine.
