Red Peak-Hold Needle
Check for excessive friction in the red peak-hold assembly by
turning the peak-hold knob in the lens counterclockwise. If
the peak-hold needle deflects the gauge needle, return the
instrument for service. Likewise, if the red peak-hold needle
moves too freely, (i.e. spins without pressure applied) return the
instrument for service.
Cleaning
Cleaning with mild antibacterial soap and water is
recommended. Do not soak or saturate the device with water.
Handle and posts can be cleaned with an isopropyl alcohol
wipe. Do not use alcohol on the plastic gauge faceplate or cover.

Hydraulics
Any sign of hydraulic oil is an indication of damage to the instrument which requires service by the
manufacturer.
Hydraulic Fluid
Lafayette hand and pinch dynamometers are filled with a biodegradable, plant based hydraulic fluid.
Under normal circumstances, the fluid is contained within the device and does not come into contact
with the user or patient. If the device is damaged, the fluid can leak out and human exposure to the
fluid is a possibility. The fluid is non-toxic and contains no chemicals known to cause cancer, birth
defects or other reproductive harm. Despite the relative safety of the fluid, precautions should be
taken to limit exposure. If exposure occurs, the following guidelines from the Material Safety Data
Sheet (MSDS) of the fluid should be followed.
• ORAL: DO NOT INDUCE VOMITING. If conscious, give 2 glasses of water. Get immediate medical
attention.
• EYE: Flush with water at least 15 minutes. Get medical attention if eye irritation develops or
persists.
• SKIN: Wash with soap and water. Remove contaminated clothing. Get medical attention if irritation
develops. Launder contaminated clothing before reuse.
•
INHALATION: Remove exposed person to fresh air if adverse effects are observed. If breathing
is labored, administer oxygen. If breathing has stopped, apply artificial respiration. If irritation
persists, get medical attention.
