Like all machines, your crossbow has metal parts that periodically require lubrication to continue to function properly. To oil the trigger mechanism on your crossbow, slide the safety knob to the rear, white, “Safe” position. Apply one drop of oil to both sides of the safety slide through the safety knob window in the trigger box. Cycle the safety mechanism forward and backward multiple times to ensure the oil spreads evenly over the internal parts. Again, with the safety knob in the “Safe” position, apply one drop of oil to the string latch through the string slot in the trigger box and cycle the safety knob forward and backward to ensure coverage. To oil the Dry-Fire-Inhibitor, apply one drop of oil to both the left and right sides of the DFI wedge just underneath the steel pin at the top. Cycle the Dry-Fire-Inhibitor up and down to help spread the oil. To lubricate the axles and cam bearings, apply one drop of oil to the top of each cam where the axle and bearings pass through. To finish, use a cotton swab to wipe away any excess oil from these parts.
