GROUNDING INSTRUCTIONS

DANGER: Improper use of the grounding plug can result in a risk of electric shock.
Electrical equipment must be grounded. If it should mal-function or breakdown, grounding provides a path of least resistance for electrical current to reduce the risk of electric shock. The vacuum is equipped with a cord having an equipment-grounding conductor and grounding plug.
The plug must be inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
If repair or replacement of the cord or plug is necessary, DO NOT connect the grounded wire to either flat blade terminal.
The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.
GROUNDING METHODSMASTERCRAFT 410-SSDAF Vacuum Cleaner -
Fig
This electric equipment is for use on a nominal 120 volt circuit, and has a grounded plug that looks like the plug illustrated in (Fig A). A temporary adaptor that looks like the adaptor illustrated in (Fig B & C) may be used to connect this plug to a 2-pole receptacle as shown in (Fig B) if a properly grounded outlet is not available.
WARNING:
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded.
DO NOT modify the plug provided with the equipment. If it will not fit the outlet,have a proper outlet installed by a qualified electrician.
Note: In Canada, the use of a temporary adaptor is not permitted by the Canadian Electrical Code.
Treat this vacuum as you would any other high grade precision made product. Dropping, unreasonable bumping across thresholds and other misuses may result in a damaged unit which will not be covered by the warranty

  2. Loosen all straps, top to bottom.
  3. Slip arms and shoulder through the shoulder and chest straps
  4. Close waist straps and tighten.
  5. Tighten the upper and loser adjustments of the shoulder and chest straps so that shoulder pads come over the shoulders but remain above the armpit.

FILTER INSTALLATION

This hazardous use vacuum has special filters installed. The 2-ply disposable paper bag filter contains the bulk of all debris and protects the remaining filters from excess dirt. The 2-ply intermediate filter is a very fine non- woven filter that extends the life of the expensive HighEfficiency Particulate Air (HEPA) filter.

  1. Remove unit from carton. Disengage clamps that hold the motor head to tank. Carefully set aside.
  2. Remove HEPA filter and intermediate filter. Set aside.
  3. Install a disposable 2-ply paper filter bag by taking hold of the free ends of the cardboard attached to the paper bag. Pull cardboard forward over the inlet fitting so that the cardboard is as close to the wall of the tank as possible.
  4. Place the 2-ply intermediate filter in position on top of the tank. Fold the edge over the outside of the tank overlapping approximately one inch.
  5. Insert the HEPA filter, being careful not to move the 2-ply intermediate filter. The filter’s sealing gasket must sit evenly on the tank rim so an air tight seal will be obtained.
  6. Replace the motor head on top of the HEPA filter seated in the top of the tank.

CAUTION:

To insure a snug fit the area around the lid and top edge of the vinyl sealing gasket is free of dirt and other foreign matter.NEVER operate the vacuum cleaner without a primary HEPA filter and 2-ply disposable paper bag in place and NEVER, NEVER without the intermediate filter in position. Motor damage, lose of operating efficiency and re-circulation of hazardous material into the work area will take place.
WHEN TO CHANGE FILTERS
2-Ply Disposable Paper Filter Bags When the 2-ply disposable paper filter bag is full, it MUST be replaced. Excessive over filling of this bag makes it difficult to remove from the vacuum tank and can result in breakage and spills.
CAUTION: Always unplug vacuum from the power source before changing filters.
2-Ply Intermediate
Filter
The 2-ply intermediate filter should be replaced with every fifth change of paper bag and whenever there is damage or a visible collection of debris on the outside of the filter.
HEPA Filter
Replace the HEPA filter when loss of vacuum continues to occur after you have checked for an obstructions in the hose or wand. Also, install a new 2-ply disposable paper filter bag and 2-ply intermediate filter.
CAUTION:
