Start-Up Procedures and Precautions
4.1 Continued
11.
The amperage requirement of your Blastrac system is detailed in the “Operator
Responsibility” section of this manual. Assure this requirement is met. If the circuit
protection is too small for the load, undue stress will be applied to the circuit and the
equipment will not operate properly. If the circuit protection exceeds the
recommendation, an unsafe condition will be created.
12. Proper grounding is critical to personnel safety . Be absolutely certain that the
green ground wire power cable is properly terminated to the site power ground bus.
If a generator is to provide power, assure that the generato
r manufacturer’s
grounding instructions are followed. Serious injury can result from inadequate
equipment grounding . Once the power cord is connected and checked, energize
the power source.
13. Check the area you are about to clean. Be sure that it is free of all debris that can
clog or damage the equipment. Be sure that the surface is moisture free. Blastrac
machinery is designed to work on clean, dry surfaces only.
14. Make certain that the abrasive control valve is in the closed position. Remove the
separator lid and check that the shot hopper is free of debris and abrasive. Remove
the screens and check the butterfly valve at the bottom of the hopper. It should be
in the horizontal position. Replace the bottom screen and add approximately eight
(8) to ten (10) pounds of abrasive. The level of this abrasive should reach the
bottom of the boxed screen.
Do not overfill. Replace the separator lid.
CAUTION: BE SURE ALL ELECTRICAL DISCONNECTS ARE
LOCKED IN THE “OFF” POSITION AND THAT ALL ROTATING PARTS
ARE FULLY STOPPED BEFORE WORKING IN PANELS.
16. Check the magnetic seals on the bottom of the blast unit for metallic contaminants
such as nuts, bolts, etc., and remove. At the operator’s station, turn the travel speed
on to drive the machine forward. Deposit a layer of abrasive on the floor in front of
the magnets. Drive the machine over the abrasive to charge the magnets with a
layer of shot. The shot will form a seal between the magnets and the floor. Remove
any excess abrasive from the floor.
