General Information
Inspection

Your Marshall equipment was thoroughly inspected before it was shipped
and should be ready to operate as soon as you have completed the set-up
procedure.

Notify Humboldt Mfg. Co. or your local agent and file a claim with any carriers
involved if you find any damage to the machine. Unpack all of the equipment
carefully to prevent loss of small items or manuals.

Physical Specification

Shipping weight: 185 lbs. (78.9 kg)
Overall height: 39"
Base dimension: 16" x 18" x 10"

Power Supply

110 VAC 60 Hz 1 phase (H-1339B), 375 watts
220 VAC 60 Hz 1 phase (H-1339B.2F), 375 watts
220 VAC 50 Hz 1 phase (H-1339B.5F), 375 watts
Check to make sure your machine has the correct voltage for your local supply.

Power Cord

Your Marshall Test Machine is fitted with a molded vinyl-grounding plug.
The cord is made of three conductors:

(American color-coding) (International color coding)
Green Ground (Earth) Green/Yellow Ground (Earth)
White Cold (Neutral) Blue Cold (Neutral)
Black Hot (Live) Brown Hot (Live)

Fuses

The Marshall Test Machine uses a slow-blow fuse that is fitted into the left side
of the machine. The replacement part number is H-1339.13.

Initial Installation

Remove the packing list and verify that all parts have been received. Normally
you will receive one crate comprised of compression frame and a calibrated
load ring (H-4454.100) 10,000lbf capacity.

Set the machine base up at the place it is to be used in the laboratory and
then check that it is level by placing a spirit level on the platen. If it is not level,
adjust the feet of the machine.

Operation

Control Panel

The control panel is situated on the front left hand side of the machine base.

Preset Speed:

2.00 in/min. (50.80mm/min.)

Direction of Travel

It is necessary to ensure that the direction of the platen (up or down) has been
correctly selected. The platen travel direction switch has three positions: up,
off, down. Before changing travel direction, you must first switch to the “off”
position and pause for a second before changing travel direction.

Maximum Travel Limits

The maximum up travel limit occurs when the loading screw extends beyond the
reach of the drive gear and remains there – it is not indicated by a light. The
down travel limit is indicated on the control panel with a red indicating light.
The machine will stop operation in that direction when this light is illuminated.
The maximum travel of the platen is 3.50" (88mm).

IMPORTANT

You must use the

toggle switch to stop test.

The machine does not

stop automatically when

the stability load is reached.

Load Ring

When a load ring is used it can be attached directly to the cross-beam using the
3/4-16 x 3" long bolt.

Maximum Load

The Marshall Compression and Testing Machine is rated at 10,000lbf (or 50kN).

Flow Measurement

Requires a Marshall Test accessory, e.g., H-1344 Flow meter with dial gage, 1"
travel, 0.001" divisions, or H-1344M with 25 mm travel and .25 mm divisions.

Load Ring Calibration

Your H-4454.100 was calibrated before leaving the factory. Periodically you
should have it re-calibrated. Humboldt provides calibration services for
these load rings, please contact us at: 1.800.544.7220, 1.708.456.6300,

1.708.456.0137 fax or [e-mail].

Maintenance

The machine and transducers should be kept clean and the machine should not
be over lubricated. Light oiling with synthetic instrument oil at most is required
on exposed spindles and threads; the jack and gear box are serviced with a
premium wheel bearing grease such as Pennzoil 707L Lubriplate Grease applied
thru the grease fitting no more than annually, or when an indication of power
train friction appears.
