6.5 Coolant tank preparation
Use of a water-soluble coolant will increase cutting
efficiency and prolong blade life. Do not use black
cutting oil as a substitute. Change cutting oil often
and follow manufacturer’s instructions as to its uses
and precautions.
1. Disconnect machine from power source.
2. Pour coolant into hole through strainer cup. Fill
tank to approximately 80% of capacity.
3. Make sure coolant hose is properly connected
at each end, and return hose is connected to
drain hole and positioned in strainer cup, as
shown in Figure 6-10.
7.0 Electrical connections
The HVBS-712 and HVBS-712D Band Saw is rated
at 115/230V power, and is pre-wired for 115 volt.
The band saw comes with a plug designed for use
on a circuit with a grounded outlet that looks like the
one pictured in A, Figure 7-1.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the band saw be connected
to a dedicated 15 amp circuit with circuit breaker or
fuse. If connected to a circuit protected by fuses, use
time delay fuse marked “D”. Local codes take
precedence over recommendations.
7.1 GROUNDING INSTRUCTIONS
This machine must be grounded. In the event of a
malfunction or breakdown, grounding provides a
path of least resistance for electric current to reduce
the risk of electric shock. This tool is equipped with
an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be
plugged into a matching outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.
Do not modify the plug provided - if it will not fit the
outlet, have the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface
that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or
replacement of the electric cord or plug is
necessary, do not connect the equipment-grounding
conductor to a live terminal.
Check with a qualified
electrician or service personnel if the grounding
instructions are not completely understood, or if
in doubt as to whether the tool is properly
grounded. Failure to comply may cause serious
or fatal injury.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
Repair or replace damaged or worn cord
immediately.
When operated at 115-volt, this tool is intended for
use on a circuit that has an outlet that looks like the
one illustrated in A, Figure 7-1. An adapter, shown
in B and C, may be used to connect this plug to a
2-pole receptacle as shown in B if a properly
grounded outlet is not available. The temporary
adapter should be used only until a properly
grounded outlet can be installed by a qualified
electrician. The green-colored rigid ear, lug, and the
like, extending from the adapter must be connected
to a permanent ground such as a properly grounded
outlet box. Note: In Canada, the use of a temporary
adaptor is not permitted by the Canadian Electrical
Code, C22.1.
Figure 7-1: grounding
When operated at 230-volt, this tool is intended for
use on a circuit that has an outlet that looks like the
one illustrated in D, Figure 7-1. The tool has a
grounding plug that looks like the plug illustrated in
D. Make sure the tool is connected to an outlet
having the same configuration as the plug. No
adapter is available or should be used with this tool.
If the tool must be reconnected for use on a different
type of electric circuit, the reconnection should be
made by qualified service personnel; and after
