ENGINE COOLING SYSTEM
WARNING
Air to cool the engine is drawn in the base sides
and exhaust through radiator & case back. It is
important that the intake and exhaust air is not
restricted. Allow a minimum clearance of 2 feet
(0.6m) from the case back and 16in.(406mm) from
either side of the base to a vertical surface.

BATTERY CONNECTION
CAUTION
Use caution as the electrolyte is a strong acid that
can burn skin and damage eyes.
--------------------------------------------------------------------------------
The RANGER® 305D is shipped with the negative
battery cable disconnected. Make certain that the
RUN-STOP switch is in the STOP position. Remove
the two screws from the rear battery tray using a
screwdriver or a 3/8" socket. Attach the negative bat-
tery cable to the negative battery terminal and tighten
using a 1/2" socket or wrench.
NOTE: This machine is furnished with a wet charged
battery; if unused for several months, the battery may
require a booster charge. Be careful to charge the bat-
tery with the correct polarity.

MUFFLER OUTLET PIPE

Using the clamp provided secure the outlet pipe to the
outlet tube with the pipe positioned such that it will
direct the exhaust in the desired direction. Tighten
using a 9/16" socket or wrench.

SPARK ARRESTER

Some federal, state or local laws may require that
gasoline or diesel engines be equipped with exhaust
spark arresters when they are operated in certain
locations where unarrested sparks may present a fire
hazard. The standard muffler included with this welder
does not qualify as a spark arrester. When required by
local regulations, a suitable spark arrester, such as
the K1898-1 must be installed and properly main-
tained.
WARNING
An incorrect spark arrestor may lead to damage to
the engine or adversely affect performance.

INSTALLATION

REMOTE CONTROL

The RANGER® 305D is equipped with a 6-pin and a
14-pin connector. The 6-pin connector is for connect-
ing the K857 or K857-1 Remote Control or for TIG
welding, the K870 foot Amptrol or the K936-3 hand
Amptrol. When in the CC-STICK, DOWNHILL PIPE,
or CV-WIRE modes and when a remote control is
connected to the 6-pin Connector, the auto-sensing
circuit automatically switches the OUTPUT control
from control at the welder to remote control.
When in TOUCH START TIG mode and when a
Amptrol is connected to the 6-Pin Connector, the
OUTPUT dial is used to set the maximum current
range of the CURRENT CONTROL of the Amptrol.
The 14-pin connector is used to directly connect a
wire feeder control cable. In the CV-WIRE mode,
when the control cable is connected to the 14-pin con-
nector, the auto-sensing circuit automatically makes
the Output Control inactive and the wire feeder volt-
age control active
NOTE: When a wire feeder with a built in welding
voltage control is connected to the 14-pin connec-
tor, do not connect anything to the 6-pin connec-
tor.

ELECTRICAL CONNECTIONS

MACHINE GROUNDING

Because this portable engine driven welder creates its
own power, it is not necessary to connect its frame to
an earth ground, unless the machine is connected to
premises wiring (home, shop, etc.)
To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power
must:
• Be grounded to the frame of the welder using a
grounded type plug.
• Be double insulated.
• Do not ground the machine to a pipe that carries
explosive or combustible material.
