TapeTech MudRunner Guía De Uso Y Mantenimiento

The MudRunner™
Place the tool at one end of the joint to be finished with the filler valve pointing away from the angle. Twist the control
tube. If using the tool for the first time, you may want to wait an instant till you see compound filling the tool. Move
the tool toward the other end of the joint, relaxing your grip on the control tube when you wish compound flow to stop.
The outlet valve will automatically close off compound flow as you relax your grip. Place the tool at the other end of
the joint and repeat, relaxing your grip on the control tube when you have overlapped the point where the previous pass
ended.
Maintenance
It is good practice to empty the tool if it is not going to be used for a time. The outlet end of the tool can be placed
in a bucket of water as is common with other tools. DON'T SUBMERGE THE HANDLE END OF THE TOOL! The
handle end can be sprayed with water, but should not be submerged. Do not directly spray the white cover at the top
end of the control tube. Should water find its way into the handle, stand the handle up vertically to allow it to drain.
Clean the tool by removing the main tube cap. Clean all compound from the inside of the cap, the filler valve, and
around the piston. If compound has gotten on the backside of the piston, then remove the main tube and clean as
needed. Lubricate the rubber piston seal with Ames® Bazooka® oil or any light machine oil.
Keep the area around the white cover clean. Avoid flushing joint compound or debris under the white cover as it
may make operation of the control tube more difficult. Lubricate the control mechanism as shown after every clean-
ing and as needed to maintain proper operation of the tool. Replace the main tube and the main tube cap as soon as
the tool is clean to reduce the chances of damaging the tool.
SYMPTOMS
1. Compound flows too quickly, finish is sloppy,
compound overflows the finishing tool.
2. Compound doesn't flow fast enough, have to
move finishing tool very slowly to get good finish.
3. MudRunner™ requires high effort to fill.
4. Compound leaks from filler valve when
removed from EasyClean® Pump.
5. Compound leaks past piston.

Operation and Maintenance Guide
"How Professionals Finish The Job"
The MudRunner™ is essentially a power assisted corner applicator and is intended
to work with all of the same tools that the corner applicator does now, primarily
with corner finishers, but also with mudheads and other tools.
Operation
In general, you will want to use joint compound thicker than you would normally
use for finishing corners. To start, it is recommended to thin the compound to
about midway between angle compound and boxing compound.
The MudRunner™ is filled with compound very much like an existing corner
applicator. Insert the filler valve fully into the discharge tube of the EasyClean®
Pump. You will need to maintain pressure against the EasyClean® Pump as the
MudRunner™ is filled or the pumping pressure will force the MudRunner™ off of
the filler valve.
Whenever there is any compound in the tool, it is under constant pressure from
the internal gas spring. Pump until the MudRunner™ piston is forced all the way
back to its stop. Once full, do not continue pumping. Attach the finishing tool
to the ball outlet of the MudRunner™ as you would with a corner applicator.
Compound flow is controlled by twisting the control tube. The more you twist, the
faster compound flows.
TROUBLESHOOTING
SOLUTIONS
1. Compound too thin. Thicken compound till excellent results
obtained.
2. Compound too thick, or control tube only partially twisted.
Ensure control tube is fully twisted to obtain full flow, or thin
compound.
3. Compound too thick, or filler valve is damaged.
4. "Trash" holding filler valve open, or valve damaged.
Use a screwdriver to fully open valve to flush "trash" out.
5. Seal or tube damage. Exchange unit.
