5.3. Turn the OPEN lever clockwise to disengage the latch mechanism and pull the lid open while holding the OPEN
lever clockwise. Releasing the lever before pulling the lid open will allow the latch to re-engage preventing the lid
from opening. (See Figure 3)
6. GAS STRUT REPLACEMENT OR REVERSAL:
**Attention: The gas strut is considered a “wear” item and may need to be replaced after a period of time.
On some models, the Lock-box is shipped from the factory with the gas strut located on the left hand side.
On these models, the gas strut may be reversed to the opposite side if desired.
6.1 To replace or reverse the gas strut, start by removing the spring clip from the top and bottom mounting heads by
prying the clip up with a flat screwdriver.
6.2 Remove the gas strut from the ball studs located at the top and bottom of the strut.
**Note the orientation of the factory installed gas strut is with the gas strut body located at the top.
6.3 If reversing the strut location, remove the (2) ball studs from the mounting flanges on the Lock-box body and
relocate to the opposite side.
6.4 Install a new or re-install the gas strut onto the ball studs and re-install the retaining spring clips.

Required Periodic maintenance: Failure to perform periodic maintenance can result in the loss of access
inside the security enclosure and failure of components.
7.1 Lubrication is required for all moving parts. The schedule will vary depending on the level of usage and
environmental conditions. Once a month is a good starting point. Be sure to lubricate all friction points
completely. Use high temperature lithium grease. Key lubrication points are shown in the illustration
below. (See figure 5)
7.2 If the latch handle is removed or has been bumped out of alignment it will need to be adjusted correctly
again. The gap shown between the knob and the stop is critical and can vary slightly. If the gap is too
small the knob cannot be turned enough to unlock the latch. If the gap is too large then the knob can be
turned past its stop point which trips the internal clutch and will not unlock the latch. Adjust the handle
so the gap is the largest possible initially then if the clutch is tripped move it in small increments until it
unlatches correctly. (See figure 6)
7.3 All fasteners should be checked to ensure they are not loose. The schedule will vary depending on the
level of usage, environmental conditions and typical vibration encountered. Once a month is a good
starting point. Loctite may need to be reapplied after extended periods of time.
