1.5 Safety – Considerations Under Normal Operation

Work on electrical parts of the machine must be preformed by a qualified electrician or by experienced persons under the supervision of a qualified electrician.

ALWAYS INFORM OPERATING PERSONNEL before starting any special work or maintenance work! When work is carried out that affects the machine's operations or settings and/or the settings of the safety devices, complete compliance with this instruction manual is necessary! This is an important part of the Lock Out/Tag Out procedure mentioned below. LOCK OUT/TAG OUT or “Maintenance Mode” of a machine. The machine must be in a “safe” mode when troubleshooting, adjusting or maintaining the equipment. The machine state is "safe” to work on when it is unable to endanger anyone, i.e. no stored energy that might be released is present. Examples would include:  Electrically the Main switch is disconnected, locked out and tagged out.  Mechanically the machine and all parts of it are secure i.e. lids cannot fall, wheels cannot roll, etc.  Any other “stored energy”, such as a spring under tension has been neutralized.

Before switching the machine ON, ensure no one can be endangered when the machine starts up!

Check to ensure that the machine power switch is in the off position before attempting to plug the machine into the main power source! Make sure that the power plug and receptacle are compatible and that they fit securely together. If they do not securely fit together, do not operate the machine!

The machine MUST be connected to an approved dust collector such as a Blastrac® 4-54DC99, 6-54DC99 or 8-54DC99 when in operation. NEVER turn off or disconnect the dust collector when the machine is running!

Always empty the dust container of the dust collector properly. Comply with waste disposal regulations. If you are unsure of current regulations contact your local authority. Always dispose of materials and supplies safely to protect the environment.

1.5 Safety – Considerations Under Normal Operation (cont’d)

AVOID DANGEROUS SITUATIONS

• Survey the work area before starting the machine for hidden

obstructions and uneven cracks or joints.

• Do not expose the machine to rain.

How to Execute an Emergency Stop:

9 Operate the Emergency Stop Pushbutton located on the control panel of

the scarifier or, for those machines equipped with a gasoline motor, activate the dead-man safety switch by pulling the rope. This will remove all power from the machine.

9 Operate the mechanical quick lift actuator on the scarifier. This will remove

the scarifier drum from the work surface.

9 Switch the dust collector to the off position. 9 Wait until all drives come to a complete stop! 9 Disconnect the main power plugs or lock out the main disconnect switches

of both machines to ensure that no power is being fed to the scarifier or the dust collector.

• Do not use the machine in standing water conditions.

• Keep work area well lit.

• Do not allow the machine to cross over the edge of the

concrete slab or work surface.

• When working on uneven surfaces, pay attention not to cross

over embedded floor anchors, ledges, or heaved slab joints as this may lead to machine damage, personal injury, or both.

Check the system thoroughly after each transport and at least once a day for external damage and defects. As defects or problems are found qualified personnel MUST correct them immediately.

In the event of an emergency, the operator should execute an Emergency Stop! A Lock Out/Tag Out or “Maintenance Mode” is necessary in the event of an emergency!

Operating Instructions BMP-(G/E)250-X Section 1 - Safety Precautions February 2006

1.6 Electrical Safety

When extending the main cable, use only extension cables that are dimensioned in accordance with the machine's total output and with current regulations.

DO NOT ABUSE THE POWER CORD! Never pull the machine by the cord! Never allow the cord to be run over by a forklift truck or any other vehicle! Connect the power cord to the power source and power cable extensions with approved plugs only and with the machine power switch turned off.

To protect against unnecessary damage, ensure that no vehicles, such as forklift trucks, can drive over the electrical cable or the dust hose!

Electrical components must be checked on an ongoing basis. Electrical cables, enclosures, and safety devices should be inspected prior to every shift, EVERY day. Always inspect after transport. A thorough check of the internal terminations should be accomplished every 3 months.

If defects are found or suspected, contact a qualified electrician or your Blastrac representative. Defects such as loose connections or scorched cables must be corrected immediately.

Ensure reliability of voltmeters used for troubleshooting.

Operating Instructions BMP-(G/E)250-X Section 3 - General Information February 2006

3.3 Mechanical Operating Elements

Quick Lift Actuator:

The BMP-G/E250-X scarifiers have a quick lift actuator for the scarifier drum (See Figure 3.1, Item 2).

The quick lift actuator can be used to lift the scarifier drum without altering the scarifier depth setting, to transport or move the scarifier or in an emergency situation.

Depth Setting Adjustment:

Turn the depth setting adjustment wheel or hand wheel to set the scarifier depth so that the individual scarifier cutters bit correctly (scratch) and the desired surface profile is obtained. The depth setting adjustment enables the scarier cutters to be set as deep as required on the surface to be treated.

The scarifier depth should only be set “deep” enough so that the scarifier cutters are thrown up without obstruction through centrifugal force and can turn freely on their individual shaft. If the depth setting has been set correctly, the scarifier will run smoothly and evenly.

3.4 Scarifier Drum Details

The scarifier drum is the heart of the scarifier. The scarifier drum has a very simple structure. The individual scarifier cutters are slid onto their individual shaft with spacer washers as shown in the enclosed assembly plan. The washers ensure that there is sufficient clearance between the scarifier cutters.

The enclosed component-mounting diagram takes into account a required lateral play of approximately 1-3mm for the scarifier cutters.

5.2 Starting (cont’d)

d) Verify that the deadman lanyard secured in place.

Connect the power cord to site power. Assure the fuse or circuit

breaker protecting this branch motor circuit does not exceed the

parameters set out in Section 2.5.

e) NOW, check the direction of rotation of the motor with the direction

marking (arrow) on the motor. This can be accomplished by quickly

turning the motor on and then back off (not applicable with gas motor). f) Start the motor by pressing the “On” switch. (If the scarifier is

equipped with a gasoline motor, please refer to the enclosed owner’s

manual for the motor.) g) Now lower the scarifier drum slowly by means of the quick lift actuator. h) The scarifying depth can now be set by means of the depth setting

adjustment wheel. Slowly increase the depth setting until the desire

surface profile is being obtained.

If excessive dust is generated, verify that the dust container of the dust collector is empty and check the dust collector hose and connections.

If the scarifying depth is too deep it will have a negative effect on the machine. Instead of more surface removal or scarifying, the machine will run unevenly and may begin to “jump”.

By slight pushing or allowing the machine to “pull itself along the surface can now be worked with very minimal effort. The operating speed, or the feed rate, will depend on the characteristics of the surface and the desired surface profile to be obtained.

Operating Instructions BMP-(G/E)250-X Section 6 – Operation February 2006

6.1 Normal Operation

Normally, starting and operating the scarifier is the same procedure as described in Section 5 “Preparation/Starting”.

Scarifying should be carried out in parallel tracks and in such a way that the dust hose and the electric cable do not become twisted. For further details, see

Section 6.3 “Recommended Scarifying Directions”.

To protect against unnecessary damage, ensure that no vehicles, such as forklifts, can drive over the electrical cable or the dust hose.

6.2 Information on the Drive Speed

Choosing the correct drive speed is crucial in order to obtain the desired surface profile. If the surface is uneven (e.g. different degrees of hardness or coatings with different thickness) the drive speed can be varied during scarifying to obtain a uniform surface profile.

The correct drive speed will depend on the material of the surface being scarified and the desired surface profile.

To select the correct drive speed:

1. Set the desired penetration depth by means of the depth setting

adjustment wheel.

2. Inspect the surface, and begin scarifying with a relatively fast drive

speed.

3. Begin to slow the drive speed until the desired surface profile is being

obtained.

7.1 Information

Before beginning any repair or maintenance work on the machine or its drive, ensue that it cannot be switched on accidentally. Set the machine into “Maintenance Mode”. See Section 1.7 “Maintenance Mode. Breakdowns caused by insufficient and unprofessional maintenance can lead to very high repair costs and long downtimes. Regular maintenance and quality-trained personnel are essential.

The machine’s service life, operational efficiency and safety depend on several factors including proper and regularly scheduled maintenance.

The Maintenance and Inspection List I Section 7.2 contains information on schedules, inspections, and maintenance for normal operation. The schedule is based on daily use of the machine. If the number of working hours shown here is not reached in the corresponding period, the period may be extended. However, a complete inspection must take place every year.

Because operating conditions can vary considerably, it is not possible to state in advance how often checks for wear, inspections, maintenance, and/or repairs are necessary. A practical inspection schedule should be drawn up, taking the operating conditions into account. Blastrac technicians are available to provide more assistance in creating a practical schedule.

This manual’s operating, maintenance and safety instructions must be complied with during maintenance and repair work. In particular, instructions provided with electrical and gasoline engine components must be complied with.

Operating Instructions BMP-(G/E)250-X Section 7 – Maintenance February 2006

7.2 Maintenance and Inspection List

The following maintenance schedule should be strictly followed to insure personnel safety, as well as proper operation and efficiency.

12 hours after repairs:

• Check all safety devices for effectiveness.

• Check all accessible screw connections for correct fit and tightness.

Daily and before starting work:

• Check all power supply cable for damage.

• Check dust collector hose for damage.

• Verify that there is no foreign material in the scarifier drum.

• Verify that the dust container of the dust collector is empty.

• Check the scarifier durm, lateral axle, scarifier cutters and housing for

wear.

• Check the tension of the gear belt; tighten if necessary. See Section 7.8

“Gear Belt”.

Yearly:

• Full overhaul and cleaning of the complete machine.

If using a scarifying machine with a gasoline motor, always comply with the enclosed owner’s manual for the motor.

7.3 Repairs

This Manual only describes repairs that occur during maintenance work or those repairs that are required when replacing worn parts.

As with starting for the first time, we recommend that our Blastrac personnel carry out the first repairs of all Blastrac machines. This allows the equipment users operating and maintaining the machine the opportunity to become extensively familiar with the proper repair procedures.

Operating Instructions BMP-(G/E)250-X Section 7 – Maintenance February 2006

7.3 Repairs (cont’d)

If for any reason the decision is made to replace parts, please comply with the following instructions in this manual and perform all work in the sequence shown.

Production losses are often more expensive than stocking critical high wear parts. Consider maintaining an inventory of critical high wear parts.

Any screws, nuts, or bolts removed must be replaced with the same quality (strength, material) and design.

Use original Blastrac replacement parts only.

7.4 Scarifier Drum

The scarifier drum is a highly stressed component of the machine and special attention should be paid to the drum during maintenance and repairs.

If the scarifier drum is replaced always clean and lubricate the drive shaft so that the next time the drum is replaced rust or deposits of dirt do not make the replacement more difficult. Reassemble using Dynatex Anti-Seize PN 49560 or Loctite Anti-Seize PN 767.

If the scarifier drum must be dismantled for new parts to be installed or components replaced, make sure that the arrangement of the scarifier cutters and spacers is maintained as shown in the enclosed components drawings found in Section 10 “Spare Parts”. In addition, make sure that the holes in the covering plate for the lateral axles are not worn out and that the screws are tight.

Page 37

Operating Instructions BMP-(G/E)250-X Section 7 – Maintenance February 2006

7.5 Scarifier Drum (cont’d)

To obtain an even, clean surface profile on the surface to be scarified:

• Ensure that the correct scarifying depth is set.

• Ensure that the machine is being driven at the correct drive speed.

• Ensure that the correct components for the scarifier drum are being used.

• Ensure that the correct scarifier cutters for that specific surface are being

used.

Incorrectly installed scarifier drum will cause unbalanced machine operation and excessive wear.

 Incorrect assembly of OEM machine parts and components voids the

equipment warranty.

 Use of non-OEM parts and cutters voids the equipment warranty.

7.6 Equipment for the Scarifier Drum

The examples of scarifier cutters enclosed within this manual have been extensively tested by Blastrac technicians and display an even scarified pattern.

The selection of cutter types and the component arrangement are among the most important factors for proper operation and efficiency of these machines.

An incorrect component arrangement for the scarifier drum leads to extreme wear rates and reduces machine performance. See Section 10 “Spare Part” for component mounting diagrams.

Operating Instructions BMP-(G/E)250-X Section 7 – Maintenance February 2006

7.6 Replacing the Scarifier Drum

Before beginning any repair or maintenance work on the machine or its drives, ensure that it cannot be switched on accidentally. Set the machine into the “Maintenance Mode”. See Section 1.7 “Maintenance Mode”. HOT! Friction caused by running this machine over any floor causes heat to build up in the scarifier tools and the scarifier drum. Use gloves when removing the scarifier drum to prevent a burn injury.

Removal:

1) Unscrew the fastening screws from the side panel and remove panel

by pulling it away from the machine housing.

2) Pull the scarifier drum off of the drive shaft.

Installation

1) Clean the drive shaft and grease it evenly.

2) Slide the scarifier drum onto the drive shaft until it comes to a stop.

When fitting the side panel back on, make sure that the bearing unit is correctly fitted into the side panel.

Never use any of these machines without the side panel and protective guards correctly fitted and installed.

7.7 Influencing the Scarifying Pattern

The appropriate scarifying pattern depends o the surface being worked on and can be influenced by varying the scarifying depth and the drive speed.

Depending on the surface to be scarified, selection of scarifier cutters, scarifying depth and drive speed will vary. A correct selection can be obtained through trial and error, preferably on an area of the surface that is not highly visible or extremely important.

Operating Instructions BMP-(G/E)250-X Section 7 – Maintenance February 2006

7.7 Influencing the Scarifying Pattern (cont’d)

After fitting new or different scarifier cutters onto the machine, always check the scarifying pattern. This is the only way to ensure operational efficiency and to protect against unnecessary repair costs.

7.8 Gear Belt

Removal:

• Remove the screws for the belt

guard and remove guard.

• If necessary, slacken the belt

tension by loosening the belt tensioner (See Figure 7.1, item #C) and remove the belt.

The gear belt is tensioned by means of a tensioner, which can be loosened and slid left or right.

Installation:

• Place the gear belt over the

motor pulley and drum pulley, then move tensioner right to tension the belt.

• Make sure that the gear belt is parallel and has the correct initial tension.

Depth of displacement should be about 3/16” when squeezing the belt by hand as indicated by the double arrow “B” in Figure 7.1.
