SET-UP INSTRUCTIONS
When the OzzieMaster monitor is used with the portable base on concrete, each spike must be "set" with the head of the safety
hook, a 16 oz. hammer or equivalent. After the OzzieMaster is hooked up to a water supply and ready to flow, set the spikes in
rotation by striking the hex head bolt, over each ground spike, with a sharp blow from a hammer or another tool sufficient to drive
the spike at least 1⁄8" (3mm) into the concrete. This process must be repeated each time the unit is repositioned on a concrete
surface. As with any portable monitor, the OzzieMaster should always be secured with the safety chain or rope before using on
any surface.
CAUTION: Wear safety glasses or face shield when setting the spikes.
The portable base is designed to grip by imbedding the ground spikes into the surface on which it is operating. These spikes will not
grip on metal, marble, or similar hard surfaces. Do not operate on these surfaces without securing the unit with a rope or some
other stable means, in addition to the safety chain.
The ground spikes in the portable base are made of a special hardened tool steel to remain sharp through extended use. If, after
use, the flats on the ends of the spikes exceed 1⁄16" (1.5mm) diameter, the spikes must be sharpened or replaced. (See Maintenance
Instruction Section)
Each spike must be in uniform contact with the ground surface at all times during use. Make sure that no large rocks or other debris
are under the portable base during use, for this may cause the spikes to come out of contact with the ground surface.
WARNING: The OzzieMaster monitor is designed with a safety stop at 45˚ above horizontal to maintain stability when
used in the portable base. Do not release the elevation stop and operate below that point unless the unit is
secured in the direct mount flange base.
A. DUAL INLET GROUND BASE
The Dual Inlet/Flange Adapter must be used with the Dual Inlet Ground Base (See Figure 2). When used with the dual inlet
base, the unit should not be operated at more than 500 GPM (1900 LPM) with one hose and 750 GPM (2900 LPM) with two
hoses. Therefore, do not exceed the following discharge pressures with straight tips unless the unit is secured in the direct
mount flange base:
Also, do not exceed 500 GPM (1900 LPM) with one hose or 750 GPM (2900 LPM) with two hoses, when using a fog nozzle,
unless the unit is secured in the direct mount flange base.
WARNING: Do not use Larger than 3" Hose for the Dual Inlet Ground Base.
Note: The two tie down straps must be added to both rear legs of the Dual Inlet Ground Base. Remove the existing ground
spike sleeve from both rear legs (See Figure 2A) and replace with the new sleeve, straps and bolt (See Figure 2A).
The following hose set-up must be used to provide necessary stability when operating the Dual Inlet Ground Base (Figure 2).
