GIRAUD POWERED CASE TRIMMER

Receiving and Setting Up

 

 
The trimmer comes complete in one caliber as it leaves the box.  Set the trimmer 
on a sturdy, level surface and examine for any signs of damage from shipping.  If 
any are found, contact Giraud Tool Company,Inc. (GTC) as soon as found.  
Together we can determine if the trimmer can be fixed or needs to be returned to 
GTC for repair.  GTC will repair or replace these trimmers for the original 
purchaser for life.  If the parts or problems are determined to be due to defective 
parts GTC made, GTC will repair or replace them free of charge.  If the parts or 
problems are determined to be due to defective parts not made by GTC, such as 
the motor or switches, GTC will replace them for you at cost or as inexpensively 
as possible.  Unfortunately, GTC cannot control somebody else's products 
against defective parts or material.  GTC will get the trimmer fixed for you as best 
as possible, no BS, simple as that. 
 
Once the trimmer is setup on a sturdy work surface with the trimmer shaft 
horizontal to the floor, plug the power cord in and make sure there are no 
hazards around the trimmer.  Check and make sure the power cord does not 
touch the rotating pulleys or belt.  Make sure there are no liquids around the 
trimmer that could cause problems with the electric motor or switch.  See Fig. 1 
below. 
 
Each trimmer is sent with a sample 
case attached to the sheet metal in 
a small ziplock style bag with the 
caliber noted.  This case was the 
last case trimmed with that specific 
trimmer before being packaged for 
shipment. There are also two 
spanner wrenches enclosed in the 
white foam packing material on the 
right side of the shipping box.  
There is usually some marking to 
help locate these wrenches before 
discarding the shipping box.   
 
Examine the sample case to see 
what a proper trim and chamfer looks like, and measure the case to determine 
what length the trimmer is currently set for.  Turn the power switch on and verify 
the motor works properly and runs without undue vibrations or noises. 
If everything appears okay, you are ready to proceed with trimming some brass.  
If the case length of the sample case is longer or shorter than your desired 
length, you can adjust it at this point using the spanner wrenches provided.  Each 
trimmer unit is now provided with engraved witness marks on the front face of the 
trimmer body.  Each of these marks are located around the case holder at 45º 
increments.  If you mark the face end of your threaded case holder with a marker 
or felt tip pen, you can determine how far the case holder is twisted in or out by 
comparing the witness marks on the trimmer to the mark on the end of the case
