Use - agratronix Hay Core Sampler Operator's Manual

Good probing principles
• Probe at random and Probe a lot
• Be careful not to contaminate the sample
• Preferred probing depth is about 10" – 20". Drill the Hay Core Sampler
about halfway through, remove the sample from the tube (either in a
bag or toss it away), drill as deep as possible from the same hole
• Take note if the tube heats up during sampling. Warm tube may
decrease sample integrity (remove moisture from it for example)
Usage
Hay Core Sampler is meant to be operated with ½" or 3/8" battery drills or
120V corded electric drills. At least 18V cordless drill is recommended. (Fig.1)
Do not wear any loose clothing when using Hay Core Sampler. Be aware
that the cutting tip is very sharp, especially when using the cleaning rod.
Use the rubber tip cover to protect the user and the tip when not using the item.
Usage of protective goggles and hearing protection is recommended.
Attach the drill chuck to the Drill Adapter. Attach zip-lock bag onto steel
cup and secure it with a rubber band. Steel cup is designed for 1 gallon
zip lock bags but also bigger bags can be used.
Press the Hay Core Sampler against the bale to be sampled. With the help
of your body weight, steadily press the Hay Core Sampler into the bale
while drilling. Apply more power if necessary. High revolutions can cause
the core sampler to heat up significantly which may affect the sample.
Exert the force through the drill for the best results.
After drilling a core sample, use cleaning rod to press the sample into the
zip lock bag. Drill more samples if necessary. The sampling depth, bale
material and bale density affect the amount of sample obtained from one
hole.
After obtaining enough samples, remove the bag from the steel cup,
press the excessive air out from the plastic bag and secure it tightly. Add
necessary markings (date, bale, crop, name, number) and store it properly.
