Engine Safety
DANGER: Engine exhaust gases contain poisonous carbon monoxide. Carbon monoxide
is odorless and colorless and can cause injury or death if inhaled. Do not use equipment
indoors without adequate ventilation. Refer to OSHA guidelines and regulations
concerning maximum levels of exposure to carbon monoxide gases and other hazards
associated with using internal combustion engines. It is highly recommended that a CO
(carbon monoxide) detector be used to warn the user if levels become unsafe.
Warning: Engine, exhaust system and hydraulic component temperatures could be in
excess of 200F causing severe burns if touched.

•To raise the Blasthead make sure the “Blasthead Free Flow”button is not illuminated, then press and hold
the “blasthead up”button (2) until the castors on the head are off the ground.
•The Clutch On Button (3) will engage the clutch and run up the blast wheel.
•The Clutch Off Button (4) will disengage the clutch turning the blast wheel off.
•The Shot Valve Open Button (5) will engage the linear actuator opening the shot valve on the blast head.
•The Shot Valve Close Button (6) will disengage the linear actuator closing the shot valve.

YOU ARE BLASTING.
Shut down
•Approximately 10 feet (distance will vary due to machine speed) from the end of your blast lane, press the
“shot valve close” button with the machine moving until the shot cycles through. DO NOT STOP THE
MACHINE UNTIL THE SHOT HAS MADE ITS WAY THOUGH THE SYSTEM. FAILURE TO DO SO WILL RESULT
IN DAMAGE TO THE SURFACE YOU ARE BLASTING.

6. Maintenance
Warning: Engine, exhaust system and hydraulic component temperatures could
be in excess of 200 F causing severe burns if touched.
Pay attention to Chapter 3 "Safety" during maintenance and repair works.
Failures due to inadequate or incorrect maintenance may generate very high repair costs and long downtimes of
the BMR-25P. Regular maintenance, therefore, is imperative.
Operational safety and service life of the shot blaster depend, among other things, on proper maintenance.
Maintenance Schedule
The time indications are based on uninterrupted operation. When the indicated number of working hours is not
achieved during the corresponding period, the period can be extended. However a full overhaul must be carried out
at least once a year.
Due to different working conditions it can’t be foreseen how frequently inspections for wear checks, inspection,
maintenance, and repair work ought to be carried out. Prepare a suitable inspection schedule considering your own
working conditions and experience.
Our specialists will be happy to assist you with more advice.
Store the cleaned and dry machine in a dry and humid free room. Protect the components from moisture, heat,
dust and shocks.
All repair work must to be done by qualified Blastrac personnel, this is to guarantee a safe and reliable machine.
Any guarantee on the machine is void when:
▪Non original Blastrac parts have been used
▪Repair work is not done by qualified Blastrac personnel
▪Changes or conversions without the express written consent of Blastrac NA

Hydraulic System Instruction
To check the oil level there is an indicator (1) installed on the side of the tank. The indicator can be seen from the
driver side of the BMR-25P under the seat behind the side panel. The level shouldn’t be lower than half the range
of the indicator.
At least one time during the year or every 150 hours the oil from system and filter should be replaced. For this
operation disconnect the battery. The oil drain hose comes out under the machine near back. You can refill the
hydraulic oil from the driver side panel. The oil filter is located on the side of the hydraulic oil tank. Before doing
any maintenance, disconnect the power and block machine in stable position.

2. Remove blasthead belt guard.
3. Remove blasthead belt.
4. Remove the hydraulic cylinder pin.
5. Remove head pivot pin.
6. Roll the head away from the machine. Use CAUTION when removing the head. Be sure to support the
head so it doesn’t tip over.
Seal Adjustment
Front and side seals must be in contact with the ground at all times and the brush should be approximately ¼”
(6mm) from the surface. If the seals are not in contact with the ground, follow the steps below.
1. Loosen the nuts that hold the seals on. They don’t have to come all the way off, just loosen to where the
seals can move up and down freely.
2. Push seals down to where they contact the ground and tighten the nuts.
Shot Consumption Adjustment
If you notice that the dust collector is consuming shot, or if you are dropping shot, the vacuum needs to be
adjusted. To do this, follow the steps below.
1. Locate the vacuum slide plate on the driver’s side of the dust collector.
2. Loosen the knobs that hold the plate in place.
3. Slide the plate to the right, opening the plate, if you are consuming shot.
4. Slide the plate to the left, closing the plate, if you are dropping shot.
5. You will have to adjust the plate as necessary.
6. Once you have made the proper adjustments, tighten the knobs, locking the plate in place.
